Secretary of State Marco Rubio suggested the US would stop helping after months of efforts had failed to bring an end to the fighting.

President Donald Trump added: ‘Now,if for some reason,one of the two parties makes it very difficult,we’re just going to say you’re foolish. You are fools,you horrible people.

‘And we’re going to just take a pass. But hopefully,we won’t have to do that.’

Trump previously claimed he could end the war between Russia and Ukraine ‘within 24 hours’.
