>> Unless they're put on notice, they're gonna be held accountable if they do not support the President of the United States->> President Donald Trump's former strategist, Steve Bannon, drawing battle lines with the top leaders of the Republican establishment. In an interview with 60 MINUTES Sunday, his first since he was pushed out of the White House last month, Bannon going after Speaker of the House, Paul Ryan, and Senate leader Mitch McConnell.
>> They do not want Donald Trump's populist, economic, nationalist agenda to be implemented. It's very obvious.>> Now that you're out of the White House, you're going to war with them?>> Absolutely.>> Domestic Policy Deputy Editor Caren Bohan is following the story.>> Well, he really is very angry at the Republican establishment figures.
Sees them as the reason for the failures that Trump has seen so far. Part of that goes to the immigration issue where leadership is much more sympathetic to the idea of comprehensive reform on immigration. And Bannon represents a wing of conservative thought that is very hardline on immigration.
Bannon is determined to see that his side of the party wins, even if it means encouraging primary challenges. And that poses a big threat to some incumbents, and may make it harder for Republicans to keep both houses of Congress next year.>> Bannon also taking a sharp jab at his former boss.
Saying Trump's decision to fire James Comey as FBI Director in the middle of the Russia probe was the biggest mistake in modern political history. The blast at Trump drawing swift pushback from the White House.>> The President was right in firing Director Comey.>> Trump's firing of Comey led to the naming of Special Counselor Robert Mueller to lead the investigation.
A jab at Trump coming as conservative news site Breitbart, Bannon's new home, has been ramping up its attacks on the President.>> Now that he's on the outside, he has a big leadership at Breitbart, and these are the very people who are Trump's core supporters. And so Trump can ill-afford to antagonize him.
>> Breitbart running the headline Meet The Swamp after Trump struck a deal with Democrats in congress last week extending the debt ceiling and funding that government for another three months.
