Former prosecutor Solomon Wisenberg compared former New York City Mayor Rudy Giuliani's (R) legal strategy to a murder-suicide on Thursday after Giuliani said in an interview that President TrumpDonald John TrumpFormer employees critique EPA under Trump in new report Fired State Department watchdog says Pompeo aide attempted to 'bully' him over investigations Virginia senator calls for Barr to resign over order to clear protests MORE reimbursed his personal attorney, Michael Cohen, for the $130,000 he paid hush money to adult-film star Stormy Daniels, who claims she had an affair with Trump in 2006.

"I liken it to a murder-suicide," Wisenberg told CNN's Dana Bash. "He metaphorically murdered the president and committed suicide with respect to his own reputation as a criminal defense attorney."

"It was an incredibly embarrassing interview. Look, when you're representing anybody, much less the president of the United States, you have to know that when you go on television and you make statements on his behalf, that's admissible in court. That's an admission by an agent if President Trump ever went into court," he said. 

Giuliani, who recently joined Trump's legal team, contradicted Trump, who previously told reporters that he was not aware of the payment. 

“It's not campaign money. No campaign finance violation. They funneled through a law firm and the president repaid it,” Giuliani told Fox News's Sean Hannity on Wednesday. 

"He didn’t know about the specifics of it as far as I know, but he did know about the general arrangement, that Michael would take care of things like this," he said.

Trump defended the payment in a series of tweets on Thursday.
