Former Utah congressman and Fox News contributor Jason Chaffetz said it's "highly suspicious" that Lanny Davis -- a longtime ally of Bill and Hillary Clinton -- is representing Michael Cohen.

Cohen, Trump’s former personal attorney and confidant, admitted Tuesday 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.

Cohen 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.

"Lanny Davis' presence here is a huge question mark," Chaffetz said on "America's Newsroom." "This is somebody with close proximity [to] Hillary Clinton and the Democratic machine. It really makes you wonder: Why is Lanny Davis sitting in the middle of all this?"

He questioned why out of all the attorneys in the world, Cohen chose Davis, who served as special White House counsel in the 1990s during the Clinton administration and recently wrote a book titled "The Unmaking of the President 2016: How FBI Director James Comey Cost Hillary Clinton the Presidency."

"I think that's highly suspicious," Chaffetz said.

He also agreed with a point made by Former Trump campaign adviser Michael Caputo, who said it's interesting that Cohen as recently as February insisted that the payments to Daniels and McDougal were on the up and up, but when he was faced with federal charges, he suddenly changed his tune.

Chaffetz said that Cohen evidently had huge financial problems, and then was facing federal charges and "mounds of legal bills."

"And then comes along Lanny Davis, Hillary Clinton's person. And how convenient that the two merge and make this Reese's Peanut Butter Cup that is supposed to the end all, be all," he said. "Huge credibility problems on this. But it is a serious situation for the president, Rudy Giuliani and his legal team."
