A CBS/YouGov poll released at the weekend even showed a 10 point advantage to Biden over his Republican rival, with the Democrat set to take the majority of swing states.

The Atlantic first reported on the anonymously sourced allegations. At a White House news conference on Monday, Mr Trump repeated his claim that the story was a "hoax" and said: "I'm not saying the military's in love with me. The soldiers are."

However, he added: "The top people in the Pentagon probably aren't because they want to do nothing but fight wars so all of those wonderful companies that make the bombs and make the planes and make everything else stay happy."
