“This president is going to try to steal this election,” Biden said in an interview on “The Daily Show with Trevor Noah.” The presumptive Democratic presidential nominee said of ensuring that the voting process is fair: “It’s my greatest concern. My single greatest concern.”

Biden was also asked whether he has considered what would happen if he wins but Trump refuses to leave office.

“Yes, I have,” he said quickly.

The interview appeared to be edited at that point, but Biden resumed by speaking about the number of high-ranking former military officers who spoke out over the past week about Trump’s response to the protests.

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