In a “60 Minutes” interview on CBS that aired Sunday, Biden said he is “very concerned” about the prospect of foreign interference in the upcoming election.

"Everybody knows what's going on. Trump not only doesn't want to do anything about it, he's going out and asking for help. ‘Come help me. Come help me defeat — keep Biden from being the nominee,’” Biden told host Norah O’Donnell.

"The Russians don't want me to be president and Trump doesn't want me to be the nominee," the 2020 candidate added.

Biden hammered Trump for previously saying Russia’s interference in the 2016 election was a hoax, even after the U.S. intelligence community and Congress confirmed the Kremlin did indeed attempt to interfere.

Biden said that Trump is "an idiot— in terms of saying that. Everybody knows this. Everybody knows it. Nobody doubts it."
