Agents on Monday seized documents from Michael Cohen regarding his payment to an adult-film star who has said she had an affair with Trump more than a decade ago. Stormy Daniels has said the payment, made shortly before the 2016 presidential election, was meant to buy her silence. A tip from the special counsel's office reportedly sparked the raid.

Trump blasted the FBI raid as a "real disgrace" and "attack on our country in a true sense."

Trump's lawyers and the special counsel's team have been discussing an interview for months as part of the probe into Russian election interference and possible collusion between the president's campaign and Moscow.

White House lawyers had reportedly begun briefing the president on potential topics the special counsel may want to cover and were still discussing whether Trump would speak under oath.

In a press conference Monday, Trump again floated the idea that he may fire Mueller, a move he previously considered that sparked pushback from lawmakers in both parties.

Trump is now "understandably less trusting" of the special counsel's legal team, one source told ABC.
