“She’s always been terrible and unfair, just like most of the Fake News reporters, but I’ll still play the game,” Trump tweeted on Saturday of the NBC News White House correspondent, who will moderate the final presidential debate on Thursday. “The people know! How’s Steve Scully doing?” Trump's tweet came in response to his son Donald Trump Jr. tweeting quote-tweeting New York Post journalist Jon Levine alleging that Welker has "deep Democratic ties." Trump's remarks stand in direct contrast to praise of Welker from one of his senior campaign staffers. “Look, I think I have a very high opinion of Kristen Welker. I think she’s going to do an excellent job as the moderator for the third debate,” said Jason Miller, a senior adviser to Trump’s campaign. “I think she’s a journalist whose very fair in her approach. And I think that she’ll be a very good choice for this third debate.” ALSO: Trump gets his supporters to boo Oprah Winfrey on the campaign trail.
