If anyone in President Donald Trump’s administration tried to influence witnesses or "produce false narratives" in the Stormy Daniels case, that could lead to obstruction charges from special counsel Robert Mueller, George Washington Law School professor Jonathan Turley said Monday.

“They have a search warrant referring to the payments of Stormy Daniels. Any effort to influence witnesses, withhold evidence, produce false narratives, could be the obstruction case that has so far evaded Robert Mueller," Turley said Monday on MSNBC’s "Morning Joe."

Turley said that it was within Trump’s authority to fire FBI Director James Comey, but the Stormy Daniels case, which involves a $130,000 payoff to the adult film star over an alleged affair with Trump, is a different situation.

"With regard to the Comey matter, it’s more complex, because the president is using his inherent constitutional powers. But with Stormy Daniels, all that falls away. If you try to influence witnesses, obstruct efforts with regard to that investigation, it’s a much clearer shot for the southern district to allege something like obstruction," Turley said on "Morning Joe."

The law professor also took aim at Rudy Giuliani’s statements about attorney Michael Cohen’s payments to Daniels.

"The Trump Administration appeared to finally recognize that Cohen had put the president in the worst possible position with his payment of hush money and incriminating past statements. Giuliani then took a bad position and made it far, far worse. He tried to reframe the payment of the $130,000 from a gift to a loan from Cohen, thereby tripping a series of new potential criminal and ethical violations without (as he seemed to assume) getting the president out of the campaign-finance threat,” Turley wrote in a Monday USA Today opinion piece.
