Joe Biden is "rarely seen" and when he is, the US President will occasionally show up and make some public comments that are "usually incoherent," says President of the Centre of the American Experiment John Hinderaker.

"He is the only president in recent times that has gone this late into his first term without addressing a joint session of Congress," Mr Hinderaker told Sky News. 

"Whoever is making the decisions in the current White House, they're on the far-left.

"That's the one thing I can tell you."
