Trump's Transportation Secretary Sean P. Duffy Launches Initiative to Eliminate Traffic Bottlenecks Across America
States will identify target areas and collaborate on plans to deliver congestion relief to American drivers
*
U.S. Transportation Secretary Sean P. Duffy and the Federal Highway Administration (FHWA) today launched the Freedom to Drive initiative: an opportunity for states to collaborate with USDOT on tackling increasing congestioncorridors across America. This national effort aims to save American families both time and money by focusing on maximizing roadway capacities, fasttracking projects that alleviate congestion chokepoints, and leveraging American technology and private-sector partnerships.
"Under President Trump, we are working to deliver less congested roads and highways to give you a little bit more time at home with your family around the dinner table," said U.S. Transportation Secretary Sean P. Duffy. "Part of ushering in a Golden Age of Travel means making it a little easier to get where you need to go. The Trump Administration is tackling congestion head on to eliminate endless traffic jams and ensure you spend less sitting wasting away in gridlock."
"The Freedom to Drive initiative exemplifies the Trump Administration's commitment to leveraging public and private sector collaboration to bring real relief to American families," said Deputy Transportation Secretary Steven G. Bradbury. "By working hand-in-hand with states to tackle our toughest infrastructure challenges, we will eliminate the bottlenecks of the past and Get America Building Again!"
"Gridlock and congestion have no place in the Golden Age of Transportation," said FHWA Administrator Sean McMaster. "The Trump Administration is calling on every Governor to join us in clearing the bottlenecks and cutting waste to save Americans both time and money. We want local solutions that serve all road users, instead of federal bureaucrats favoring one mode of travel over another."
In his letter, Secretary Duffy emphasized the Administration's commitment to moving away from "stop-and-go" policies and toward high-performance, high-efficiency solutions. The Secretary requests Governors identify two to five of their states' worst congestion bottlenecks and outline actionable steps to address them.
To support these efforts, the FHWA has launched the Freedom to Drive website as a central resource for technical tools and congestion-relief strategies.
The Case for New Infrastructure to Reduce Traffic:
* America is home to 10 of the 25 most congested cities in the world, including Chicago and Los Angeles.
* In 2024, the average urban auto commuter spent 63 hours stuck in traffic. That equals $269 billion in lost productivity.
* Not only are Americans losing valuable time with their families and loved ones, but delays to commercial and freight activity also impacted the economy.
* This problem is not contained to major metropolitan cities, but rural areas also face disruptions due to crashes, severe weather, and recreational travel.
Additional Information:
Rebuilding America's aging highway infrastructure is estimated to cost nearly a trillion dollars. Leveraging private sector partnerships allows taxpayer dollars to go further while delivering new transportation infrastructure safely and efficiently.
In August 2025, USDOT modeled this partnership when the Department announced a loan of up to $3.89 billion from the Build America Bureau to a public-private partnership between the Georgia Department of Transportation (GDOT), the State Road and Tollway Authority (SRTA), and SR 400 Peach Partners, LLC (Peach Partners), to add new lanes in both directions along a 16-mile section from the Metropolitan Atlanta Rapid Transit Authority (MARTA) North Springs Station to one mile north of McFarland Parkway.
The project is expected to reduce delays by over 19,000 hours each day, or about 15 minutes per traveler, due to less idling and traffic congestion. It will also enhance public safety through the construction of new bridges and other safety improvements, the replacement or widening of several existing bridges, and will reduce traffic incidents by an estimated eight percent. This project will offer travelers new choices. The new express lanes will be tolled using dynamic congestion pricing to manage demand and maintain reliable trip times, while current lanes will remain free.

WASHINGTON, April 21 -- The U.S. State Department issued the following news release:

PEPFAR Data Release
For decades there has been the problem with how policymakers think about PEPFAR's data: by measuring how much treatment U.S. taxpayers pay for, not progress made actually fighting and eliminating the disease for patients.
The U.S. Department of State has released PEPFAR program data on Spotlight (http://data.pepfar.gov/?_gl=1*1etx1h8*_gcl_au*MTMyMzczOTU1Ni4xNzc2NzY5OTY1) and on the Department's PEPFAR website (https://www.state.gov/pepfar) covering the period of July 1, 2025 - September31, 2025. This report reflects a transition-year baseline, including the absorption of USAID PEPFAR programming to the Department of State and shows that as a result of our America First Global Health Strategy, we are continuing to save lives while also protecting taxpayer dollars.
PEFFAR-supported programs provided anti-retroviral (ARV) treatment for 20.6 million people living with HIV in more than 50 countries--stable from the same FY 2024 reporting period.
Additionally, PEPFAR initiated 103,000 pregnant and breastfeeding women on pre-exposure prophylaxis--more than double the 43,000 from a year ago. This represents critical early progress toward President Trump's goal of ending mother-to-child transmission of HIV.
Three million people now receive treatment from national governments rather than external PEPFAR implementers--more than 2 million successfully transitioned during July 1 to September 31, 2025 alone.
What is misrepresented as a significant decline in the number of children on HIV treatment is actually a sign of the tremendous progress that has been made reducing the incidence of mother-to-child transmission of HIV and is consistent with historical trends. Over the past four years, the number of children on treatment has declined from 643,627 in 2022 to 508,703 in 2025--declines of 7 percent, 7 percent, and 9 percent over the past three years respectively. We are optimistic these declines will continue, especially with the U.S. Government's funding of Lenacapavir, which can further prevent mother-to-child transmission (not reflected in this point-in-time data from last year).
The lower number of positive tests is a sign of the progress that has been made battling the HIV epidemic and is consistent with historical trends. Over the past four years, positive tests declined from 1,693,349 in 2022 to 1,136,488 in 2025--declines of 14 percent, 12 percent, and 11percent over the past three years respectively. This data does not include the impact of the bilateral agreements we have signed and the broader strategies being implemented under the America First Global Health Strategy.
The message is clear: we cut overall spending by 30 percent while preserving critical frontline HIV care and eliminating wasteful programs. This proves the America First Global Health Strategy works. In the coming months, we expect the data to show more lives saved per taxpayer dollar. The narrative will shift as our strategic approach demonstrates that ending the HIV/AIDS epidemic requires fewer taxpayer dollars--not more.

News - SETAF-AF team drives bottom-up innovation, transforms operational data management
VICENZA, Italy -- A three-person tiger team launched in February 2025 has helped transform U.S. Army Southern European Task Force, Africa (SETAF-AF) into the Army's premier battle lab in Africa. The team now helps the command lead by transforming operational data into fast, actionable decisions. The team integrates machine learning to fuse information from external sources. This platform replaces fragmentedworkflows with automated decision support for commanders, enhancing real-time situational awareness.
The push for this system began after an extended joint task force operation spanning multiple geographic combatant commands. A subsequent after-action review revealed severe data silos and a fractured information environment across the staff. "Staff relied on scattered PowerPoints and inconsistent network drives, causing widespread confusion," said U.S. Army Lt. Col. Kevin Ong, the SETAF-AF influence branch chief. "We lacked a central location for all parties to determine the actual ground truth."
In response, SETAF-AF's G3 operations directorate tasked Ong to lead a "tiger team." Starting with three staff members, a limited budget and no dedicated engineering support, they studied data-mature commands like U.S. Indo-Pacific Command and U.S. Central Command. The team borrowed use cases and adapted strategic-level tools to fit operational requirements.
"It felt like being a substitute teacher," Ong said. "You read the lesson a day ahead and then try to teach the rest of the staff the next day." Over the past year, the team built or tailored approximately a dozen tools to make users more efficient. For example, the "Scribe" tool uses artificial intelligence to transcribe meetings, identify speakers and generate action items for staff officers.
SETAF-AF Smart Search enables staff members to query command-specific classified documents without exposing sensitive data to external AI models. Its success has prompted other commands to develop their own tailored versions.
A tailored decision support matrix gives a commander a structured, data-driven framework to evaluate operational courses of action using live feeds. Rather than sifting through disconnected reports, that commander sees competing options ranked side by side against near real-time data, enabling faster, more confident decisions.
This platform dismantles historical information silos and automates manual analytical processes. Its tools slash the time required for administrative tasks and compresses workflows that once took trained staff members days to complete into minutes.
Across every tool, Ong's team prioritizes machine-human teaming, ensuring that automation focuses on data aggregation and pattern recognition, while the user reviews, interprets and decides. "We created tools that flag important activity in near real time, cutting analyst time from hours to minutes," Ong said. "The commander gets intelligence while it is still actionable."
The team's solutions have reached far beyond SETAF-AF, and U.S. Africa Command has since explored integrating Scribe into key meetings across its staff. Ong's team also acts as a force multiplier for subordinate units. When a unit under U.S. Army Europe and Africa identified a meeting-transcription requirement, the SETAF-AF tiger team built and delivered the capability. According to Ong, fulfilling this capability request saved the unit over 40 hours of internal development time. "Our mission requires us to stay adaptable," Ong said. "Handling multiple operations at once forces us to find smarter ways to work." By December 2025, internal demand outpaced the original mandate of the tiger team. The team transitioned into a permanent subordinate component of the newly established Advanced Capabilities Directorate, where it was rebranded as the Operations Data Division. The overall directorate serves as the command's front door for the innovation ecosystem, translating senior-leader vision into battlefield-ready capabilities through technical scouting and coordination with industry and academia.
Today, the Operational Data Division comprises five people organized into two sections: operations research and systems analysis officers who verify and structure incoming data, and platform builders who develop applications. To extend its reach, the team supports dedicated platform builders within each staff section across the command, creating a distributed network that ensures continuity and operational ownership.
During the upcoming African Lion 26 exercise, the team will use the system to build shared situational awareness with over 40 partners and allies. This massive multinational effort validates the sensor-to-shooter loop, features multilanguage reporting generation and reinforces interoperability across Africa. "The idea is to have all our partners and allies in one room looking at the same sheet of music," Ong said.
For a command managing missions from crisis response to multinational exercises, the Advanced Capabilities Directorate proves the value of bottom-up innovation.

WASHINGTON, April 21 -- The Securities and Exchange Commission has issued an order to suspend George John Drazenovic, a Chartered Professional Accountant, from appearing or practicing before the Commission as an accountant. This action follows the entry of a final judgment against Drazenovic in a separate civil action regarding his involvement in penny stock schemes.
Drazenovic, a resident of Burnaby, British Columbia, Canada, previously served as Chief Financial Officer for Sun Cal Energy Inc., Oramed Pharmaceuticals Inc., and Tornado Gold International Corp. According to the Order InstitutingPublic Administrative Proceedings Pursuant to Rule 102(e) of the Commission's Rules of Practice, Making Findings, and Imposing Remedial Sanctions (3-22628), Drazenovic submitted an offer of settlement which the Commission accepted.
The Commission findings indicate that on February 24, 2026, the United States District Court for the Southern District of New York entered a final judgment against Drazenovic. This judgment permanently enjoined him from future violations of the Securities Act of 1933 and the Exchange Act. The court ordered Drazenovic to pay $331,595 in disgorgement of ill-gotten gains, $51,050 in prejudgment interest, and a $236,451 civil money penalty.
The original complaint alleged that between April 2010 and October 2019, Drazenovic participated in pump and dump schemes involving penny stocks. He acted as a finder of mineral properties that functioned as assets for various issuers used as vehicles for fraud. In exchange for these services, Drazenovic received proceeds from stock sales during misleading promotional campaigns. These payments were made on a furtive basis while the stock prices were artificially inflated. Under Rule 102(e), the Commission maintains authority to suspend any accountant who has been permanently enjoined by a court for misconduct in an action brought by the Commission. Consequently, Drazenovic is now barred from practicing before the Commission, effective immediately, to protect the public interest and maintain the integrity of financial reporting.

Muon g-2 Experiment Pioneers Win Breakthrough Prize in Fundamental Physics
Recognition honors experiments and scientific collaborations at three institutions that explored the subtle wobble of a subatomic particle
Editor's note: The following news release is being issued jointly by the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, DOE's Fermi National Accelerator Laboratory, and CERN, the European Organization for Nuclear Research.
*
The Muong-2 Collaborations at CERN -- the European Organization for Nuclear Research -- and two U.S. Department of Energy National Laboratories -- Brookhaven National Laboratory and Fermi National Accelerator Laboratory (Fermilab) -- are the recipients of this year's Breakthrough Prize in Fundamental Physics. Over a period of more than 60 years, experiments at these three renowned research institutions pursued a quest to measure, as precisely as possible, the subtle wobble of the muon -- a tiny subatomic particle that offered an opportunity to test physicists' fundamental understanding of particles and forces.
The Breakthrough Prize Foundation citation recognizes the awardees' "multi-decade, groundbreaking contributions to the measurement of the muon's anomalous magnetic moment, pushing the boundaries of experimental precision and igniting a new era in the quest for physics beyond the Standard Model."
The prizewinners are the living co-authors of the publications that reported the results from the measurement campaigns at CERN, Brookhaven, and Fermilab. The $3 million prize will be split among all living co-authors at all three institutions.
Two pairs of scientists representing the experiments at Brookhaven and Fermilab will accept the prize on behalf of the group at a gala celebration at the Barker Hangar in Santa Monica, California, on Saturday, April 18, 2026. They are: William M. Morse of Brookhaven Lab and Bradley Lee Roberts of Boston University, who helped lead the "Muon g-2" experiment at Brookhaven from construction in 1990 to the publication of final results in 2004; and Chris Polly of Fermilab and David Hertzog of the University of Washington, who helped lead a follow-up "Muon g-2" experiment at Fermilab from 2013 through publication of final results in 2025. The award also recognizes an earlier series of "g-2" experiments conducted at CERN from 1959 to 1979.
Popularly known as the "Oscars(R) of Science," the Breakthrough Prizes were created in 2012 by a group of Silicon Valley innovators to recognize the world's top scientists working in the fundamental sciences -- the disciplines that ask the biggest questions and find the deepest explanations. Additional prizes were awarded in a variety of categories, including the life sciences and mathematics.
Background: mystery of the muon
The muon has been a bit of an enigma since its discovery in 1936. It shares certain characteristics with electrons, including its negative charge and a form of internal magnetism, dubbed "g," but is 200 times heavier. Was it just a heavy cousin of the electron, or something else? Measuring its magnetism might point to clues.
Early calculations suggested the value of g should be two for both electrons and muons. But experiments in the 1940s revealed that electrons have a tiny bit of extra magnetism. Physicists expressed this "anomalous magnetic moment" as "g-2," to represent the amount that g differs from the calculated value of two. Over time, physicists realized that the electron's tiny deviation from two is caused by interactions with a sea of "virtual particles" popping in and out of existence.
By measuring the g-factor of muons, physicists could see if these interactions were affecting muons, too. If they observed more deviation than expected, that discrepancy might point to a hole in their understanding of the virtual particles causing the magnetic disturbance -- and possibly the existence of yet-to-be-discovered particles.
Method: comparing measurements with predictions
The experiments at all three institutions recognized by this prize were driven by this same basic principle: measure the muon g-2 value with the highest precision possible and compare those measurements with the best predictions available at the time. They all used a similar experimental setup: sending a beam of muons into a magnetic ring and using sensitive detectors to measure the degree to which these tiny spinning particles began to wobble, or "precess," away from perfect alignment as they sailed around the ring.
Results: from CERN, Brookhaven
Three separate experiments at CERN from 1959 to 1979, each with increasing precision, measured the muon's g-factor as slightly higher than two, exactly as predicted by the theory-based calculations. This confirmed the predictions and firmly established the muon's identity as a heavy cousin of the electron.
Improved experimental techniques and expanded knowledge of particles and forces motivated new muon g-2 experiments. That's when Bill Morse and Lee Roberts entered the scene. Together with Vernon Hughes of Yale University (deceased in 2003), they built and led the "E821 g-2" experiment at Brookhaven Lab.
When the first Brookhaven Muon g-2 experiment results were published in 2001, it set off a worldwide spark of excitement. The findings revealed a tantalizingly larger-than-predicted anomaly, but not enough of a difference between experiment and theory to claim a discovery. Results published in 2002 improved the precision of Brookhaven's measurement. The final result, published in 2004, deviated further from the prediction, but was still just a hint that muons might be affected by something unknown.
The continuing mystery launched an effort among physicists to improve the precision of both the theoretical predictions and the experimental measurements.
Fermilab: moving muons to Illinois
In 2013, under the guidance of Morse, Roberts, David Hertzog, and Chris Polly -- working with a large international team -- Brookhaven Lab's g-2 muon storage magnet embarked on an epic land-and-sea journey from Long Island, New York, to Fermilab outside of Chicago. There, it was set up to repeat the experiment using Fermilab's higher-intensity muon beam and new state-of-the-art technologies.
In parallel, an international collaboration of theorists formed the Muon g-2 Theory Initiative to improve the theoretical calculation. In 2020, the Theory Initiative published an updated, more precise muon g-2 prediction based on a technique that uses input data from other experiments.
The discrepancy between experiment and the prediction from that technique continued to grow in 2021 when Fermilab announced its first experimental result, confirming the Brookhaven result with a slightly improved precision. At the same time, a new theoretical prediction came out based on a new technique that heavily relies on computational power. This new predicted value was almost in agreement with the experimental measurement, suddenly narrowing the discrepancy.
The theory: a new discrepancy
Recently, the Theory Initiative published a new prediction combining the results of several groups that used the new computational technique. This prediction agrees with the experimental measurement, dampening the possibility that muons will point to "new physics." However, theorists will continue to work to understand this new discrepancy -- not between experimental measurements and predictions but between the data-driven and computational approaches for making the predictions.
Is there still a possibility that the muon's magnetic moment could be a harbinger of new physics? The mystery continues. But either way, the Breakthrough Prize is a testament to the ever-increasing precision of these experiments and the persistence of the researchers in their quest to pursue an answer.
