Washington (CNN) Former Vice President Joe Biden said Thursday he believes President Donald Trump will try to delay November's presidential election.

"Mark my words: I think he is gonna try to kick back the election somehow, come up with some rationale why it can't be held," Biden said at a virtual fundraiser, according to a pool report. Biden has maintained the November election should not be postponed and has previously made similar comments.

"Those are the incoherent, conspiracy theory ramblings of a lost candidate who is out of touch with reality," Tim Murtaugh, communications director for the Trump campaign, said in a statement Friday. "President Trump has been clear that the election will happen on November 3rd."

Fears over the coronavirus and its spread have increased concerns over how the election will be held safely, with new calls to expand access to voting and voting by mail. Biden said Congress needs to ensure that states have sufficient funding for expanded voting options during the pandemic.
