Trial lawyer tells CNN that Giuliani's bumbling cable news spots have put Trump in 'significant legal peril'
President Donald Trump and Rudy Giuliani

Trump attorney Rudy Giuliani's bumbling cable news interviews aren't just good fodder for late-night comedians -- they also might be adding to President Donald Trump's legal jeopardy.

During an appearance on CNN Monday, trial attorney Seth Berenzweig argued that Giuliani's frequent cable news spots are harming Trump legally far more than they might be helping him politically.

"I think Mr. Giuliani is putting his client in significant legal peril," he said. "If you take a look at what's going on right now, there are a lot of unforced errors. Just focus on the situation right now with Don McGahn -- there could be arguments either way about whether the president wanted to waive privilege, whether he could or should, but at the end of the day, that's not necessarily a bad strategy. What is utterly shocking is that, when you waive privilege, and then you find out that Don McGahn has been speaking with the special counsel's office for 30 hours and you're reading about it when you find out about it in the New York Times? That's absolutely shocking."

Berenzweig then went on to hammer the Trump administration for believing they could still claim executive privilege over McGahn's testimony even though they've already made him available as a witness.

"Once waived, it's waived permanently," he said. "There's a lot of misdirection going on and the president is in significant legal peril."

Toward the end of the segment, the attorney took one more shot at Giuliani's competence.

"He doesn't know the facts, he doesn't know the case, he doesn't know the law of his own case," he said.
