Acting White House chief of staff Mick Mulvaney undercut President Trump’s claim that there was no quid pro quo in the decision to withhold aid from Ukraine. Jeff Mason, a White House correspondent for Reuters, Amber Phillips, who covers Congress for the Washington Post, and Christina Ruffini, a CBS News foreign affairs reporter, spoke to CBSN’s “Red & Blue” about Mulvaney’s comments, as well as the deal struck with Turkey on a ceasefire in Syria.
