investigation came in early march. during negotiations over a possible interview between donald trump and bob mueller. and it was in early march that we learned about the first signs of problems on trump's legal team. on march 10th, "the new york times" reported that trump had approached bill clinton's impeachment lawyer, emmitt flood. the president responded to that news account with a tweet slamming the paper and praising his own attorneys, john dowd, thai bob, and jay sekulow. dowd, the main counsel handling the mueller investigation, left the legal team later in march. a friend of donald trump told "the washington post" that dowd was frustrated when the president ignored his advice to refuse an interview with the special counsel. the president has repeatedly expressed his willingness to talk to mueller. >> mr. president, will you testify to special counsel robert mueller, sir? >> i would like to. >> are you going to talk to mueller? >> i'm looking forward to it,
