Kurt Bardella, a political consultant who resigned Friday as spokesman for Breitbart News over the organizations's handling of the Michelle Fields-Corey Lewandowski situation, on Friday night accused his former client of lying about it.

"You're saying they're lying?" CNN host Don Lemon asked Bardella, who barely hesitated.

"Yes, I am," Bardella said.

Lemon then asked Bardella why the organization wouldn't support the allegations of its own employee, Fields, who has filed a police report against Lewandowski, who she says grabbed her arm violently. Breitbart on Friday morning ran a story suggesting someone besides Lewandowski probably was responsible for the bruises on Fields's arm, but she and Washington Post reporter Ben Terris remain steadfast that it was Lewandowski. Lewandowski and the Trump campaign have denied the entire episode and sought to impugn Fields's character.

Friday afternoon, video emerged that backed up Fields's and Terris's version of events.

Bardella said he thinks Breitbart is waffling because it simply has too much invested in Trump, who it has openly and unabashedly supported for months.

"When you've gone all in so much for a candidate, when you have that kind of skin in the game, you don't want to see that derailed," said Bardella, who added that he personally doesn't support Trump and that it was part of his problem with Breitbart.

Bardella added that Trump's treatment of violence at his rallies is "completely unbecoming of someone who wants to be president of the United States," calling it "ridiculous, absurd and ... dangerous."

"Donald Trump makes me embarrassed to say that I'm a Republican," Bardella said.
