WASHINGTON — U.S. Food and Drug Administration Commissioner Marty Makary on Tuesday became the latest member of President Donald Trump’s administration to leave their post this year. 

“I want to thank Dr. Marty Makary for having done a great job at the FDA. So much was accomplished under his leadership,” Trump wrote on social media. “He was a hard worker, who was respected by all, and will go on to have an outstanding career in Medicine. Kyle Diamantas, a very talented person, will be put in the Acting position.”

Diamantas was working as the deputy commissioner for food, leading the program that focuses on nutrition and food safety.

Health and Human Services Secretary Robert F. Kennedy Jr. wrote in a social media post that Makary “pushed forward critical reforms and helped advance our mission to Make America Healthy Again.”

“I also want to thank Kyle Diamantas for stepping in as Acting Commissioner — his leadership has already delivered remarkable wins on the MAHA food agenda, and I have full confidence in his continued work,” Kennedy added. “We have an outstanding team at FDA, and the work continues without pause. The search for a new Commissioner is already underway, and we will move forward with urgency.”

Makary’s resignation marks the fourth time a senior member of the Trump administration has either left or been forced out during the last few months. 

Kristi Noem was ousted as Homeland Security secretary in early March, moving to a different job as a special envoy. Pam Bondi resigned as attorney general in early April to move back to the private sector. And Lori Chavez-DeRemer stepped down as Labor secretary in late April, following scandals.

The Senate voted to confirm Makary to lead the FDA in March 2025, with Democratic Sens. Dick Durbin of Illinois as well as Maggie Hassan and Jeanne Shaheen of New Hampshire supporting him. 

Medication abortion

Makary’s decision to leave the FDA comes several months after anti-abortion organizations and some Republicans in Congress called for Trump to fire him over his record on access to medication abortion. 

Marjorie Dannenfelser, president of Susan B. Anthony Pro-Life America, and Lila Rose, founder of Live Action, both released statements in December pressing for the FDA to restrict access to mifepristone. 

“The FDA needs a new commissioner who will immediately reinstate in-person dispensing as it existed under President Trump’s first term and immediately conduct a comprehensive study,” Dannenfelser wrote in a statement at the time. “Commissioner Makary is severely undermining President Trump and Vice President Vance’s pro-life credentials and their position that states should have the right to enact and enforce pro-life protections. Makary must go.”

Missouri U.S. Sen. Josh Hawley sent a letter to Makary the following day urging him to wrap up a review of the current prescribing guidelines for mifepristone. 

Their frustration followed a Bloomberg Law news article that said Makary didn’t want to release the results of the study until after November’s midterm elections, which will determine which political party controls Congress for the next two years.
