Live from NPR News in Washington, I'm Windsor Johnston. President Trump has fired Homeland Security Secretary Kristi Noem in the first major Cabinet shakeup of his second term. Trump says he's planning to replace her with Senator Mark Wayne Mullins. The Oklahoma Republicans spoke to reporters outside of the Capitol shortly after the announcement was made today.
[00:37]
Senator Mark Wayne Mullins
I am super excited about this opportunity. It came at a not a complete surprise, but it came at a little bit of surprise for us. And so the president and I, as you guys know, we're great friends and we get along great. I look forward to working with him and his Cabinet. Of course, we still got to go to this little thing called confirmation.

Senator Mullen will take over as Homeland security secretary on March 31st. He'll need Senate confirmation to serve in the role permanently. Noem is expected to move into a newly created administration role focused on a security initiative called Shield of the Americas. President Trump says he wants to play a direct role in choosing the next leader of Iran, similar to the approach he took with Venezuela. NPR's Danielle Kurtzleben reports.

One potential successor to the former supreme leader, Ayatollah Ali Khamenei, is his son, Mojtabah Khamenei. But Trump firmly opposes that choice, telling Axios they are wasting their time. Khamenei's son is a lightweight. I have to be involved in the appointment, like with Delsey in Venezuela. Delsey is Delsey Rodriguez, who served as Venezuela's vice president before the US Deposed President Nicolas Maduro. Rodriguez is now Venezuela's acting president. Earlier this week, Trump told reporters most of the candidates he and his team wanted to succeed. Iran's supreme leader had already been killed in the conflict.

The U.S. war with Iran continues to rattle global energy markets. NPR's Scott Horsley reports. That's leading to higher prices at the gas pump.
[02:32]
Scott Horsley
Gasoline prices jumped by another nickel a gallon overnight, pushing the national average to $3, 25 cents a gallon. AAA says gas prices have jumped by about 25 cents over the last three days and are now about 15 cents higher than this time last year. Crude oil prices are also climbing as the US War with Iran disrupts tanker traffic in the Middle East. A specialized trade court has ordered the Trump administration to refund tens of billions of dollars worth of tariffs that the Supreme Court ruled were collected illegally. The process for repaying that money still has to be worked out, but so far, courts have slapped down effort to slow walk the process. Scott Horsley, NPR News, Washington.

You're listening to NPR News from Washington. The Department of Health and Human Services says 53 medical schools across the country have agreed to require students to complete 40 hours of nutrition education. The initiative is aimed at fighting chronic disease, which affects roughly 60% of people in the United States. Currently, the National Academy of Sciences recommends medical schools provide at least 25 hours of nutrition training. A new study suggests that certain drugs for diabetes and weight loss can lower the risk of addiction. NPR's John Hamilton has more on research in the medical journal the BMJ.

John Hamilton
The study looked at data on more than 600,000 people with type 2 diabetes. All were in the VA health system. Dr. Ziad Al Ali of Washington University in St. Louis says those treated with GLP1 drugs like Ozempic were less likely to be diagnosed substance use disorder.
[04:09]
Dr. Ziad Al Ali
They had less risk across several addictive substances, including opioids, cocaine, nicotine, alcohol, cannabis and other substances.
[04:19]
John Hamilton
For most of these substances, the risk was about 15 to 20% lower. The study also found that people with a history of addiction were less likely to overdose or require emergency treatment. Alilly says the results are promising, but need to be confirmed in controlled trials. John Hamilton, NPR News.
