Singer and actor Robert Davi took a piece out of fellow actor Robert De Niro Tuesday, saying his comments at Sunday’s Tony Awards were inappropriate.

Some people think Robert De Niro needs to learn some R-E-S-P-E-C-T when it comes to talking about President Trump! #TMZ pic.twitter.com/wvUljM8CyE — TMZ (@TMZ) June 12, 2018

Davi, speaking to TMZ, proceeded to deliver a fiery rebuke of De Niro’s impromptu speech, saying, “It was disgusting. He shouldn’t have done it. It’s art, art unites people, it doesn’t separate people. No matter how you feel about a president … or a candidate … you know, this is still America, and we should at least have respect and a certain decorum.”

But then the “Die Hard” actor lowered his sunglasses and addressed De Niro directly, taking a much harsher tone. He said, “It was disgusting what you did, Mr. De Niro, I respect you as an actor, but it was disgusting what you did, all right? And everyone who stood up. That’s my feeling.” (RELATED: Trump Hits Robert De Niro Square In The Jaw With New Nickname)

Davi started to walk away, but turned to make one last point. He said, “I didn’t agree with President Obama, but I respected him. I met him, we shook hands. All right? You don’t do that, you don’t … alienate people like that.”
