George Clooney gave his backing to Meryl Streep’s scathing attack on Donald Trump, informs The Guardian.

Trump took to Twitter on Monday to describe Streep as overrated after she used her platform at the Golden Globes to condemn his imitation of a disabled reporter and accuse him of spreading hate and violence.

"Aren’t you supposed to be running the country?" said Clooney in response. "I didn't vote for him, I don’t support him, I don’t think he’s the right choice.

"At this moment in our lives we have to hope that he doesn’t destroy everything. The reality is you have to hope he will do a decent job because if the United States fails, really terrible things happen, so you have to hope that he can."

But he added: "I don’t see any signs of it."

Clooney suggested that after a lucky run of previous presidents including Jefferson, Lincoln, Roosevelt and Kennedy, America had got "a little unlucky with Bush" and that "I think we’re going to be a little unlucky now."

Clooney was speaking at a reception for a Netflix documentary, the White Helmets, which follows the lives of the rescue volunteers in Syria. The actor recently acquired the rights to make a fiction film based on the documentary, but said it was still in very early stages.
