The former Vice President warned the next US presidential debate should not go ahead if Mr Trump does not fully recover from coronavirus. Mr Biden made the remarks as he arrived for a campaign speech in Hagerstown, Maryland. It comes after the President was discharged from hospital after only three days after testing positive for COVID-19.
Mr Biden spoke to reporters ahead of his campaign speech to pour cold water on hopes for the next debate.
He said: “I think if he still has COVID we shouldn’t have a debate.”
But despite Mr Trump’s diagnosis, the Democrat still said he was ready to go.
He added: “I’m not sure what President Trump is all about now. I don’t know what his status is.
“I’m looking forward to being able to debate him, but I just hope all the protocols are followed.”
When asked about how he felt the next debates should be handled in the wake of the White House outbreak, Mr Biden touted more protections against coronavirus.
He said: “I think what they’re doing at the Harris debate, I’ve been told, I don’t know this for fact, they’re using plexiglass, and are following what the Cleveland Clinic says.”
Kamala Harris, Mr Biden’s choice for Vice President, will debate Mr Trump’s second Mike Pence on Thursday.
Mr Pence’s representatives have refused to accept a plexiglass partition between him and Ms Harris at the debates.
Mr Trump has recently stated his desire to push ahead with the next debate, despite still recovering from coronavirus.
The President said: “I am looking forward to the debate on the evening of Thursday, October 15th in Miami. It will be great!”
It comes after the President was discharged from Walter Reed hospital after only three days.
Mr Trump claimed he was “feeling great” after his treatment, and added: “Will be back on the Campaign Trail soon!!!”
Mr Trump was confirmed positive for the virus just days after the first debate in Cleveland, Ohio.
Scientists believe coronavirus carriers are infections for two to three days before developing symptoms, leading some to speculate the President could gave exposed Mr Biden to the virus.
But Mr Biden’s campaign claimed the Democrat treated negative for the virus after the debate.
The US has seen 7,495,674 cases and 210,784 deaths from coronavirus as of October 7.
