Whatever Rudy does for the president, I hope he is better prepared and more discreet than Michael Cohen. Cohen seems to talk way too much to the press, and reacts too predictably when criticized. Cohen apparently had lots of physical tapes of pre-recorded conversations stored in his office that was raided. He should have anticipated Mueller taking that step.
This has been going on for a year.
The president needs better lawyers. I understand many of the top lawyers have declined to represent the president. Possibly, due to his reputation for spontaneous tweeting to the public in ways that could undermine a carefully crafted defense.
And I really haven't heard him talk to the press.
And this has nothing to do with the Mueller investigation.
