Stormy Daniels's lawyer Michael Avenatti went after President Trump's lawyer Rudy Giuliani on Saturday by asking for someone to provide evidence that Giuliani has watched pornography.

"I want to test Mr. Giuliani's claims of being adamantly against pornography and having no use for adult film stars. If anyone can provide me with any evidence of him voluntarily viewing pornography, I will protect you as a source and publish it," Avenatti wrote on Twitter. "Let's PROVE the hypocrisy."

Avenatti's request came in response to comments Giuliani made Wednesday at the "Globes" Capital Market Conference in Israel in which he said he did not respect women who act in pornographic films.

"I respect women - beautiful women and women with value - but a woman who sells her body for sexual exploitation, I don't respect," Giuliani said. "Tell me what damage she suffered. Someone who sells his or her body for money has no good name."

Avenatti responded to Giuliani's comments on Thursday by calling him a "pig."

"Mr. Giuliani is an absolute pig for making those comments, he's basically stating that women that engage in the adult-film industry and other forms of pornography don't have reputations and are not entitled to respect," Avenatti said during an appearance on CNN.

"I certainly hope that we are not going to reach a place where Rudy Giuliani is going to be the police who is going to decide which women deserve respect or not," he said, adding to Trump should fire Giuliani.

Both men have tangled in the past, with Giuliani calling Avenatti an "ambulance chaser" and a "jerk," while Avenatti has called Giuliani a "complete embarrassment."

At Wednesday's conference, Giuliani went on to deny Daniels's claims that she had an affair with Trump in 2006.

Daniels has sued the president to release her from a nondisclosure agreement she signed with Trump's longtime personal attorney, Michael Cohen, in 2016.

The agreement, Daniels says, was made to keep her silent about her alleged affair with Trump. Cohen has since acknowledged to paying Daniels $130,000 days before the 2016 presidential election as part of the agreement.
