"When you reach a point where you can't give 100% to people you represent, it's not tenable to continue representing them,” Bardella said in a statement to The Hill.

Bardella, a former spokesman for Rep. Darrell Issa Darrell Edward IssaDCCC reserves new ad buys in competitive districts, adds new members to 'Red to Blue' program Wife of former Rep. Duncan Hunter sentenced to 8 months of home confinement Harris endorses Democrat in tight California House race MORE (R-Calif.), also implied that Breitbart’s handling of the incident at the Trump event was his main reason for leaving.

“My own personal observation is that there is a cycle of behavior that is escalating and it's happening exclusively at Donald Trump events,” he said in the statement. “It is wrong, disgusting and indicative of an ugliness that is contaminating the public and political discourse in our country. Life is too short to invest your time in things you don't believe and aren't passionate about. That is why I made the decision to resign from representing Breitbart."

Michelle Fields, a Breitbart reporter covering Trump’s campaign, filed a criminal complaint against Trump campaign manager Corey Lewandowski Corey R.

Her account was also backed up by Washington Post reporter Ben Terris, who was profiling several Trump staffers, including Lewandowski.

On Friday, Breitbart published an article that called into question Fields’s story, suggesting that she had misidentified Lewandowski and that someone else had grabbed her.

Buzzfeed reported later on Friday that Bardella left the company.
