of dirt on hillary clinton, but sources tell me and my colleagues that cohen says he was in the room and donald trump jr. shared the information about that meeting with his father. and cohen is willing to tell all of this to the special counsel, robert mueller. if true, it means the president has repeatedly lied about an event at the very center of the probe into possible collusion with russia. i'm going to get reaction from kremlin critic bill browder and democratic congressman jerry conley. our correspondents and analysts also standing by. first, to cnn white house correspondent abby phillip. the president's only response to this story has been his favorite venue, twitter. >> reporter: that's right, jim. the president not saying a whole lot with his own mouth about the controversies swirling around him and his administration. he left just a few minutes ago to go to bedminster, where his golf resort is, and refusing to take questions from reporters. the ruptured relationship with his personal attorney, michael cohen, is becoming a growing problem for him.
