Stormy Daniels's attorney on Thursday said President TrumpDonald John TrumpHannity urges Trump not to fire 'anybody' after Rosenstein report Ben Carson appears to tie allegation against Kavanaugh to socialist plot Five takeaways from Cruz, O'Rourke's fiery first debate MORE helped his client's case "exponentially" by claiming not to have any knowledge of the $130,000 payment his personal attorney made to the porn star days before the 2016 election.

"We very much look forward to testing the truthfulness of Mr. Trump's feigned lack of knowledge concerning the $130k payment as stated on Air Force One. As history teaches us, it is one thing to deceive the press and quite another to do so under oath," Michael Avenatti said in a tweet. 

"Good (actually GREAT) things come to those who wait!!!" he added in another. "The strength of our case just went up exponentially. You can't have an agreement when one party claims to know nothing about it."

"This is a gift from the heavens this afternoon," Avenatti said during an appearance on MSNBC. "I mean I could think of few things that would be better for our case than the statements the president made on Air Force One."

"Surely he now knows about the $130,000 payment," he continued.

Trump, for the first time on Thursday, publicly acknowledged the scandal regarding Daniels's claim that the two had an extramarital affair, telling reporters on Air Force One that he did not know where his attorney Michael Cohen obtained the funds to pay Daniels, whose legal name is Stephanie Clifford.

The money was part of an agreement to stop her from publicly discussing her affair with Trump and was made in the days before the 2016 presidential election. 

"You’ll have to ask Michael Cohen. Michael is my attorney. You’ll have to ask Michael," the president said.

Cohen has maintained that Trump had nothing to do with the settlement agreement and that the funds did not come from the president or his businesses. Cohen previously told ABC News that "the funds were taken from my home equity line and transferred internally to my LLC account in the same bank."

Daniels is arguing in court that the nondisclosure agreement is void because Trump did not sign it.
