New York, New York - Actor Robert De Niro is once again speaking out against presidential candidate Donald Trump, comparing him to some of history's worst political figures before Elon Musk jumped in to defend the politician from the actor.

De Niro recently sat down for an interview with MSNBC host Stephanie Ruhle, who asked his thoughts on Trump running for re-election while fighting a criminal court case.

The actor described it as "absurd," but said he was hopeful that the most recent case "could be it for him."

Trump has been in New York City in recent weeks, as he is facing 34 felony charges for allegedly falsifying business records in an effort to hide payments made to adult film star Stormy Daniels in order to cover up an affair he has long denied.

De Niro explained that he believes Trump is "a sick person" and "a monster" who shouldn't be allowed near the White House, as he believes it would bring "chaos beyond our imagination."

He went on to call him "pure evil" and compared Trump to two of the world's most infamous dictators – Adolf Hitler and Benito Mussolini.

"These guys, I don't know why, they look like clowns. Somehow people, that element of society, identifies with them," he said of Trump's MAGA supporters.

When asked if he would ever consider playing the former president in a movie, De Niro cut the question short, quickly stating, "Never."

"There's nothing about him – there's not one redeeming thing in him that I can see," he said.

De Niro has never been shy about his views on Trump and has openly expressed them in the past.

Last November, the actor criticized the former president in a speech, calling him a "charlatan" and a "racist."

Trump responded on his Truth Social platform, calling the actor "a total loser" and a "mental midget."

De Niro's latest remarks about Trump did get the attention of billionaire Elon Musk, who took issue with the actor comparing Trump to Hitler.

"Well, Trump was actually already president for 4 years and his policies bore no resemblance to those of Hitler, so this makes no sense," Musk argued, though De Niro did not directly compare the two politicians' policies or views.

"In fact, with the Abraham Accords, he made some progress towards peace in the Middle East, which was definitely not high on Hitler's agenda," he added.
