Washington •The shifting White House explanation for President Donald Trump’s decision to withhold military aid from Ukraine drew alarm Friday from Republicans as the impeachment inquiry tested their alliance.
Trump, in remarks at the White House, stood by his acting chief of staff, Mick Mulvaney, whose earlier comments undermined the administration's defense in the impeachment probe. Speaking Thursday at a news conference, Mulvaney essentially acknowledged a quid pro quo with Ukraine that Trump has long denied, saying that U.S. aid was withheld from Kyiv to push for an investigation of the Democratic National Committee and the 2016 election.
