President Trump ousted Secretary of Veterans Affairs David Shulkin Wednesday, announcing his intent to nominate the White House physician, Admiral Ronny Jackson, to fill the post and ending weeks of speculation about when the embattled cabinet official would leave the administration. Trump tweeted a confirmation of the news, which was first reported by Reuters. Jackson has been a White House physician to both presidents Trump and Barack Obama. Undersecretary of Defense for Personnel and Readiness Robert Wilkie will serve as interim secretary until Jackson is confirmed by the Senate, Trump said in a follow-up tweet.
