Avenatti was sentenced Thursday to prison for wire fraud and aggravated identity theft for cheating his former client Stormy Daniels out of $300,000.
"I'm very disappointed in the jury's verdict. I look forward to a full adjudication of all of the issues on appeal," Avenatti told CNN.
Avenatti is accused of using nearly $300,000 of adult film star Stormy Daniels' tell-all "Full Disclosure" for payroll and personal expenses.
Michael Avenatti questioned Stormy Daniels on stories of ghost encounters she told on her "Spooky Babes" show after living in a house she said was haunted.
"I hired a new attorney because he stole from me and lied to me."
Avenatti's trial focuses on allegations that he stole money from advanced payments made to Daniels related to her 2018 book "Full Disclosure."
"You will learn that the defendant was desperate for money," prosecutors stated during opening arguments.
Speaking under house arrest, the celebrity lawyer, who represented Stormy Daniels in her case against Trump, discussed his own downfall.
California prosecutors say Avenatti cheated five clients out of almost $10 million by negotiating and cashing in on settlements on his clients' behalf.
Delaware Third Circuit Judge Stephanos Bibas stated in an order and memorandum that Fox News coverage of Avenatti's 2018 arrest that didn't result in prosecution wasn't sufficient enough to meet the criteria of defamation.
The celebrity lawyer was found guilty in a jury trial of extortion, transmission of interstate communications with intent to extort and wire fraud.
Michael Avenatti's lawyers told a judge on Wednesday they felt six months behind bars would be a sufficient sentence after his "epic fall" led to public ridicule.
Avenatti, who had previously represented adult film actress Stormy Daniels, was convicted Friday for trying to extort money from Nike.
High-profile attorney Michael Avenatti denied attempting to extort Nike for more than $20 million after federal prosecutors in New York charged him.
"@MichaelAvenatti, if you plead fast enough, you might just get to share a cell with Michael Cohen!" Trump Jr. tweeted.
"We have discovered substantial evidence that he and certain enablers engaged in systematic witness intimidation, evidence tampering, physical threats, and payments to witnesses."
"Mr. Kelly is a predator and a criminal who has prayed on young, vulnerable girls for far too long. The time has come for him to finally be held accountable for his actions."
At a hearing, the judge did not issue a ruling but seemed to favor Trump and his attorneys' view that the suit no longer had legal grounds.
"Of all the cover-up options, spray-on is THE WORST. Even worse than utilizing Michael Cohen," said Avenatti.
"Is it true (asking for about 100 million friends)?" Avenatti tweeted at Trump Jr.
Attorneys representing the president are seeking legal fees of hundreds of thousands of dollars from the adult film actress.
"I think the field is shaping up to be even more advantageous for someone like me, not less," said the lawyer and Trump critic.
"To all the people that want to divide us for their own agendas: It is not going to happen," Avenatti wrote.
Avenatti has also floated the idea of suing TMZ for an article about an alleged domestic violence incident.
Politics, Daniels said, was a "much dirtier" business than pornography.
The Fox News host said that his daughter was confronted by the man while on an evening out at a country club.
