In a statement released by The White House today, President Trump announced his plan to nominate Stephen Hahn, M.D. to the position of FDA commissioner. Hahn is a radiation and medical oncologist, and currently serves as the chief medical executive at The University of Texas MD Anderson Cancer Center in Houston.

According to reports, current Acting FDA Commissioner Ned Sharpless will return to his position as director of the National Cancer Institute while HHS official Brett Giroir will step in at FDA until Hahn is confirmed. The Washington Post reports that Sharpless’ term ends Friday, and it could only be extended if the White House named a successor—however, the White House cannot do so because paperwork has not been completed.
