The former spokesman for Breitbart “News,” Kurt Bardella, is speaking out about the ugly ideology of Donald Trump’s new campaign chief, Stephen Bannon: Former Breitbart Staffer to Powerhouse Politics: Bannon Ran Meetings That Sounded Like White Supremacists Talking.

“If anyone sat there and listened to that call, you’d think that you were attending a white supremacist rally,” said Bardella, citing what he called Bannon’s “nationalism and hatred for immigrants, people coming into this country to try to get a better life for themselves.”

“This is someone who has a very low moral compass,” he said of Bannon, “and the idea that this is the type of person that Donald Trump, as the Republican nominee, as president, would have closest to him is very disturbing.”

Bardella joined this week’s episode of “Powerhouse Politics” podcast with ABC News Chief White House Correspondent Jonathan Karl and ABC News Deputy Political Director Shushannah Walshe to discuss the recent shakeup in the Trump campaign.

“I think it’s incredibly concerning and dangerous actually to have someone have this kind of influence with the person who is running for president of the United States, who would be a top adviser if he were to win the election,” he cautioned.
