A former rival of Donald Trump's is offering to defend him in his Stormy Danels "hush money" trial.

Michael Avenatti, who represented Daniels in her highly publicized legal saga against Trump, told the New York Post that has been in touch with Trump's legal team about testifying.

"The defense has contacted me," Avenatti said. "I'd be more than happy to testify, I don’t know that I will be called to testify, but I have been in touch with Trump’s defense for the better part of year."

The contacts were "confirmed" by a Trump source, the Post said.

It's a stark reversal for Avenatti, a former darling of the anti-Trump left.

At the height of his fame during Trump's presidency, Avenatti was a fixture on CNN and MSNBC and was even considered a presidential contender.

His fortune turned when he was charged and eventually convicted for defrauding his clients, including Daniels, and extorting Nike.

Avenatti, who is serving 19 years in prison, compared himself to Trump and said they are both targets of weaponized justice.

“I’m really bothered by the fact that Trump, in my view, has been targeted. Four cases is just over the top and I think there’s a significant chance that this is going to all backfire and is going to propel him to the White House,” he said.

“I’m not saying any of this because I’m seeking a pardon,” Avenatti added.

Unreliable witness

Trump has long denied having an affair with Daniels, who received $130,000 in "hush money" through Trump's former lawyer Michael Cohen.

Avenatti called his former client an unreliable witness and warned she would perjure herself in court, pointing to her claim that she can communicate with dead people.

“I don’t know how you can possibly put someone who makes those claims on the witness stand and use them as a star witness in a case against a former president United States who’s running for president. That is just absolutely ludicrous to me," he said.

Daniels dismissed Avenatti as a "lunatic" and a "scumbag."

“I was about to say that I also wish I’d never met him but I’m actually glad because I’m the one that helped convict him so he couldn’t steal from even more unsuspecting clients,” Daniels said.
