WATCH: Biden Says His Biggest Fear Is That Trump Will ‘Steal’ The Election

Former Vice President Joe Biden claimed Wednesday that his biggest concern about the general election is that President Donald Trump will attempt to “steal” it by limiting access to voting.

“My single greatest concern…This president is going to try to steal this election,” Biden, the presumptive 2020 Democratic nominee, said, in an interview on Comedy Central’s The Daily Show With Trevor Noah.

Biden noted that Trump, who repeatedly claims that mail-in ballots promote fraud and diminish the legitimacy of elections, used one in the Florida primary earlier this year.

The president’s allegations emerge as several state elections have tapped mail-in procedures as the coronavirus grips the U.S.

“This is the guy who said all mail-in ballots are fraudulent — voting by mail — while he sits behind a desk in the Oval Office and writes his mail-in ballot to vote in a primary,” Biden said.

Trump has repeatedly asserted that voting by mail will destroy the GOP.

Republicans should fight very hard when it comes to state wide mail-in voting. Democrats are clamoring for it. Tremendous potential for voter fraud, and for whatever reason, doesn’t work out well for Republicans. @foxandfriends

Election officials say that overall cases of mail-in voter fraud are exceedingly rare. There is no evidence to bolster Trump’s theories.

Still, Trump’s assertions have raised concerns among Democrats that the president will refuse to leave the White House if Biden wins.

During the interview, Noah questioned Biden about Trump possibly refusing to leave office. Biden said that he believed military intervention would be used.

“I am absolutely convinced they will escort him from the White House with great dispatch,” Biden said.
