"This guy should not be president. Period," he said of Trump.

Stelter then asked De Niro about criticism Fox News had leveled at the actor after he previously took aim at the president, for which De Niro had a strong response.

"F--- 'em, f--- 'em," De Niro replied.

De Niro continued to slam Trump's presidency and the country's current political climate.

"We are at a moment in our lives, in this country, where [Trump] is like a gangster. He's come along, and he's said things, done things — we say over and over again, 'this is terrible,'" he said.

"We are in a terrible situation, and this guy just keeps going on and on and on without being stopped," De Niro added.
