NBC legal analyst and George Washington University law professor Jonathan Turley warned on Morning Joe Monday that Michael Cohen turning against Donald Trump is legally dangerous for the president.

It was reported last week that Cohen, Trump’s former lawyer, claims the president knew about the Trump Tower meeting between Don Jr. and a Russian lawyer during the 2016 campaign, despite repeated denials.

“I think the Cohen development is very serious,” Turley said. “He’s one witness away from a potential catastrophe. If any of those five witnesses breaks and supports Michael Cohen, this is going to get real bad, real fast.”

“It’s not that the meeting will establish a crime of collusion, even if what Cohen is saying is true, but what it would mean is that Donald Trump Jr. would be in serious jeopardy of a criminal charge,” Turley continued. “If Mueller was to go after Donald Trump Jr., I think we would see a very rapid chain of events and it would not end well for anyone.”

He predicted that Trump would “match his past visceral language with similar action.”

“He could start to fire people, and that would have a cascading effect,” Turley said. “It would probably take us right to the doorstep of impeachment.”
