Former White House strategist Steve Bannon feels "jacked up" and is preparing for a fight since he was fired earlier Friday.

"Now, I'm free," he told the Weekly Standard. "I've got my hands back on my weapons. Someone said, ‘It's Bannon the Barbarian.' I am definitely going to crush the opposition. There's no doubt. I built a fucking machine at Breitbart. And now I'm about to go back, knowing what I know, and we're about to rev that machine up. And rev it up, we will do."

Just hours after his ouster, Breitbart News announced Bannon was back as executive chairman.

The former Trump adviser left Breitbart in 2016 to join Trump's presidential campaign.

In a separate interview, Bannon said he's prepared to "go to war" with Trump's enemies in the media and on Capitol Hill.

But he doesn't expect Trump's presidency will be the same now that he's out of the White House.

"The Trump presidency that we fought for, and won, is over," Bannon told the Weekly Standard. "We still have a huge movement, and we will make something of this Trump presidency. But that presidency is over. It'll be something else. And there'll be all kinds of fights, and there'll be good days and bad days, but that presidency is over."
