‘Serious illness’: Joe Biden’s presidential future in doubt after COVID diagnosis

Former White House chief of staff Mick Mulvaney has speculated on whether US President Joe Biden will make it to the Democratic National Convention in a month's time.

“It’s not lost on me that this morning Joe Biden gave an interview saying the only thing that would get him out of the race was a serious illness,” Mr Mulvaney told Sky News US Politics Analyst Joe Hockey.

“And then afternoon, he announced he had COVID – it’s not lost on me.”
