The research by the White House Counsel’s Office, which was triggered by a congressional impeachment inquiry announced in September, includes early August email exchanges between acting chief of staff Mick Mulvaney and White House budget officials seeking to provide an explanation for withholding the funds after the president had already ordered a hold in mid-July on the nearly $400 million in security assistance, according to the three people familiar with the matter who spoke on the condition of anonymity to discuss internal White House deliberations.
One person briefed on the records examination said White House lawyers are expressing concern that the review has turned up some unflattering exchanges and facts that could at a minimum embarrass the president. It’s unclear whether the Mulvaney discussions or other records pose any legal problems for Trump in the impeachment inquiry, but some fear they could pose political problems if revealed publicly.
