Sen. Lindsey Graham issued a "word of caution" on Fox & Friends on Tuesday after Michael Cohen's attorney, Lanny Davis, admitted to being an "anonymous" source in a story about the infamous 2016 Trump Tower meeting.

Davis told BuzzFeed News that he "made a mistake" in being a source in the July CNN story, which reported that Cohen claimed the president knew about the meeting in advance.

Davis had said on the network last week that the story's reporting "got mixed up" and that he was not the source.

Davis spent recent days walking back his bombshell assertions that Cohen could tell Special Counsel Robert Mueller that Trump had prior knowledge of the meeting.

Graham (R-S.C.) would not say Davis lied, but did say that his story simply does not "hold water."

"A lot of people try to convict President Trump. Don’t be so fast," Graham said. "I’ve seen no evidence of collusion after two years. Mueller’s looking at it. We’ll see what he says."

Donald Trump Jr. had told the Senate Judiciary Committee that he didn't tell his father about his meeting with a Russian lawyer to discuss potentially damaging information on Hillary Clinton.

Rudy Giuliani, the president's lawyer, said last month on "Outnumbered" that Cohen's claims that Trump Jr. told his father about the meeting were "categorically untrue."

Cohen admitted to violating federal campaign finance laws in 2016 by arranging hush money payments to adult film star Stormy Daniels and former Playboy model Karen McDougal “at the direction” of then-candidate Trump.

He pleaded guilty to five counts of tax evasion, one count of making false statements to a financial institution, one count of willfully causing an unlawful corporate contribution, and one count of making an excessive campaign contribution.
