Hollywood veterans Robert De Niro and Arnold Schwarzenegger clashed publicly at a cocktail reception held in LA this week, with De Niro flat out refusing to pose for a photo with the action star.
"If you're supporting Trump, I want nothing to do with you," De Niro announced when asked to pose for a snap with the actor turned Republican politician at the Friends of the Israel Defence Forces Western Regional Gala in Los Angeles.
According to Variety, De Niro then continued asking Schwarzenegger, "Are you voting for Trump? Are you voting for Trump?", before backing off to another side of the room before the former California governor had a chance to answer.
"If you're not part of the solution, you're part of the problem," De Niro was quoted as saying at the event.
While Schwarzenegger is a lifelong Republican, he publicly announced last month that Trump would not be getting his vote in tomorrow's US election.
"For the first time since I became a citizen in 1983, I will not vote for the Republican candidate for President."
Elsewhere this week, De Niro attended the Hollywood Film Awards on Sunday night and used his time on stage to again call out Trump, encouraging those in attendance to vote for Hillary Clinton.
Robert De Niro said a Donald Trump victory in the US presidential election would be a "tragedy", as the actor was honoured at the Hollywood Film Awards.
The Oscar-winning star urged Americans to vote for Hillary Clinton as he compared Trump to the "totally insane" General Jack D Ripper from Stanley Kubrick's Dr Strangelove.
"It's two days until a frightening election. The shadow of politics is hanging over us whether we like it or not," he said on Sunday.
"It's hard for me to think about anything else so let me lay it out right here. We have the opportunity to prevent a comedy from turning into a tragedy. Vote for Hillary Tuesday."
The Raging Bull actor, 76, has previously voiced opposition to Trump, saying he wanted to punch the Republican candidate in the face in a video campaign last month.
