Former advisor to President Richard Nixon, John Dean, was labeled a "rat" by President Donald Trump in a tweet this weekend. But Politico reported Dean has been speaking with Michael Cohen's attorney Lanny Davis, who "has been reaching out regularly."

Cohen has indicated he might be willing to cooperate with Robert Mueller's investigation into the possible conspiracy with Russians during the 2016 campaign.

“I reached out to my old friend John Dean because of what he went through with Watergate, and I saw some parallels to what Michael Cohen is experiencing. I wanted to gain from John’s wisdom,” Davis said when asked for comment by Politico. “I certainly don’t want to raise expectations that Mr. Cohen has anything like the level of deep involvement and detailed knowledge that John Dean had in the Nixon White House as a witness to Nixon’s crimes, but I did see some similarities and wanted to learn from what John went through.”
