"Pls ignore the shades, gold watch, smug look, private jet, and sheer cockiness. Trust me - they really do care about you. What a joke."

Parscale tweeted a point-by-point defense in response to Avenatti on Saturday.

Trump ran much of his campaign on drumming up support among white, working-class voters, a demographic which helped propel him to victory in the 2016 presidential election.

Avenatti represents Daniels, whose real name is Stephanie Clifford, in her lawsuits against the president and his former personal lawyer, Michael Cohen.

Daniels is suing Trump over a nondisclosure agreement that was meant to keep her quiet about an alleged affair with him in 2006. She is also suing Trump for defamation in his denial of their alleged relationship.

Avenatti has repeatedly ripped the president in numerous cable news appearances.

Earlier this week, he penned an op-ed for The New York Times in which he laid out the case for why Trump could be indicted.

“The fact that Mr. Trump is a sitting president should not derail a process that applies to all Americans, regardless of stature or station. He would still have the post-indictment relief available to all citizens, including the ability to challenge the constitutionality of the indictment,” Avenatti wrote.

His attacks against Trump have coincided with public statements about his potential bid for president in 2020. He said to The Hill earlier this year that the Democratic Party needs "a street fighter … someone that can give as good as they take.”
