Washington, October 21 (RHC)-- U.S. President Donald Trump will not leave office “graciously” if he loses the 2020 presidential election against Democratic nominee Joe Biden, says his former national security adviser John Bolton.

Bolton, who was fired by Trump and turned against him, made the comments in a CNN interview.  “I think it’s very troubling [Trump] has said, ‘I can’t lose unless there’s fraud,’” Bolton said.  “Of course he can lose in an honest election.”  John Bolton further warned: “Let’s be clear.  Trump will not leave graciously if he loses.  He will not leave graciously.  Whether he carries it to the extreme, I don’t think we know.”

Despite being officially nominated by the Republican party, Bolton asserted that Trump is not a conservative or a Republican.

National polls currently show Trump trailing Democratic nominee Joe Biden although surveys of electoral battleground states are tighter.

Trump has repeatedly claimed that mail-in ballots lead to mass voter fraud and that if he loses, it means the election is rigged.
