President Donald Trump's private defense lawyer on Friday lashed out at the president's former chief White House attorney.

Rudy Giuliani, the former mayor of New York City who volunteers his time as Trump's television defense lawyer, blasted former White House counsel Don McGahn during an interview with The Washington Post.

“The narrative is written as if it’s all true and somebody proved it. Nobody proved it,” Giuliani said. “I’m frustrated by the report because in some ways I’d love to have a trial and prove that it’s not true.”

Giuliani presented a theory that McGahn would have quit his job if Trump was doing anything nefarious.

“If McGahn thought any of those things were crimes, why did he stay there?” Giuliani asked.

"The guy is a very good lawyer. If he believed that there was something illegal, he wouldn’t have stayed in his job," Giuliani argued.

There is also palace intrigue over the targeting of McGahn.

"Several Trump advisers said they believed McGahn was being unfairly targeted inside the West Wing because of past tensions with Kushner and Ivanka Trump," The Post noted.
