Daniels, whose real name is Stephanie Clifford, signed the hush agreement after she was paid $130,000 by Trump's longtime personal lawyer, Michael Cohen, to keep quiet about the alleged dalliance in the weeks before the presidential election.
In the tweet, Mr. Trump says he will now "go after" Daniels and her lawyer, Michael Avenatti, who he referred to as "3rd rate". She will confirm the letter she signed!
But as Avanetti pointed out, Trump's legal troubles with the actress are far from over.
In a second tweet, Daniels referenced her book Full Disclosure.
"Bring everything you have, because we are going to demonstrate to the world what a complete shyster and liar you are", Avenatti tweeted minutes after Trump.More news: Netflix stock soars on stellar Q3 report

Daniels was quick to hit back with a rebuttal, accusing Trump of demonstrating his "incompetence, hatred of women and lack of self control on Twitter". "How many other women did you cheat on your wife with while you had a baby at home?" he tweeted. He argued Monday that Daniels has presented herself as Trump's "political adversary" in public and in court filings and that Trump has the right to respond to her claims.
On Monday, Warren thought she'd put the matter to bed when she answered a wager originally proposed by Trump himself, producing DNA results to show that she does indeed have a sliver of Native American genes.
"That's not a very nice thing to say about a lady you made brief, sputtering love to after being spanked by a magazine with your face on it is it?"
Trump tweeted that the man was "nonexistent" and that Daniels was playing the "fake news media for fools". And perhaps a penchant for bestiality.
Avenatti and Daniels have joined the ranks of Trump's chief antagonists since the beginning of this year, when Daniels' nondisclosure agreement was first reported.
"Look at that face", Trump was quoted as saying as he watched Fiorina during a television interview.
