Author Douglas Murray has questioned “who exactly is running” the United States following concerns about US President Joe Biden’s age and cognitive abilities.

“The question that is on everybody’s lips in America is who then is running the country – who exactly is running it?” Mr Murray told Sky News host Danica De Giorgio.

“Who’s running it after 4pm in the afternoon or whenever it is that we’re told that Biden starts to wind down for the day – are they confident about waking him in the night? Clearly not.

“It’s very troubling – what the American public have seen growing for a long time, in which the Democrat media have had to admit since the catastrophic debate with Trump the other week, is that Biden is not on top of his game to say the very least.

“Where is the direction of the country? Where is the security for the country? All we get are these sort of miffed and peeved answers from the White House.

“These are questions that should be asked and furthermore there are questions that should be answered.”
