The actor sounded plenty fed up Saturday night according to reports—and not because Gary Busey got tossed off Celebrity Apprentice.
So what got the Goodfella feeling so bad?
During an interview about his film career with NBC's Brian Williams tied to the Tribeca Film Festival, which the actor helped found, the conversation strayed into politics and the notoriously tight-lipped interviewee reportedly got more talkative.
Discussing the recent near government shutdown, De Niro took a moment to draw a distinction between President Barack Obama, whom the actor stumped for 2008, and others in Washington, D.C.
"This is crazy," said the actor, according to Movieline. "And I know Obama was trying to bridge the gap. His intentions are really good. Maybe some things are not as good as we all would like, but his intentions were right. A lot of these guys, they're intentions are not even good. They're just playing the game. And they're playing with people's lives."
The issue of the president's birth certificate, especially seemed to get De Niro fired up.
"I won't mention names, but certain people in the news the last couple weeks, just, what are they doing? It's crazy. They're making statements about people that they don't even back up," said De Niro, per the website. "Go get the facts before you start saying things about people."
Williams asked if De Niro was talking about the Celebrity Apprentice host (and possible presidential candidate), and De Niro reportedly confirmed he was.
"It's like a big hustle. It's like being a car salesman. Don't go out there and say things unless you can back them up. How dare you? That's awful to do. To just go out and speak and say these terrible things? Unless you just wanna get over and get the job. It's crazy."
