President Trump announced Friday that he has selected outgoing Rep. Mark Meadows (R-N.C.) as his next White House chief of staff, tapping one of his most stalwart congressional allies to run the White House as he navigates a global health crisis in a reelection year. “I have long known and worked with Mark, and the relationship is a very good one,” Trump tweeted shortly after arriving at his South Florida resort, where he is spending the weekend. Meadows replaces acting White House chief of staff Mick Mulvaney, who is being appointed the U.S. special envoy for Northern Ireland, Trump said in a follow-up tweet. The president thanked Mulvaney for “having served the administration so well.” The envoy position has been vacant under the Trump presidency.
