"I don't think Mr. Cohen has tremendous incentive to lie at this point. He did before, but I don't think he does now," Heck said, referring to Trump's former longtime attorney Michael Cohen.

"I think in fact what's happening is the walls are closing in on President Trump. He knows it, and we're going to see increasing[ly] desperate rhetoric, behavior on his part."

"This reminds me of the allegations that President Trump didn't know about the payoff to Stormy Daniels," Heck said. "Except, as it turns out, Michael Cohen did have proof. So I'm just sitting here like everybody else, waiting for the next shoe to drop."

Cohen shocked many in Washington this week with the revelation that he had secretly recorded multiple conversations with Trump. CNN aired a recording made by Cohen of the attorney and Trump discussing a payment for the rights to the story of Karen McDougal, an ex-Playboy model who claims she had an affair with Trump in 2006.

On Thursday, CNN reported that Cohen claimed Trump had advance knowledge of the June 2016 Trump Tower meeting where Russian lawyer Natalia Veselnitskaya was expected to offer dirt on Clinton, despite past denials from Trump and the White House.

The president insisted in a series of tweets Friday that he did not know about the 2016 meeting involving his son Donald Trump Jr. while accusing Cohen of making up the claim to get himself out of legal trouble amid scrutiny from federal investigators in New York.
