The White House and Capitol Building in Washington have been strengthened in anticipation of political violenceIn some states, the National Guard remained on duty to suppress the protests.

The Capitol has been closed to public tours after police arrested a man who “smelled like fuel” walking through security while carrying a torch and flares.

Philadelphia police said they had received reports of “people physically blocking the entrance to the polling place.”

Georgia Secretary of State Brad Raffensperger said a series of bomb threats in the Atlanta area were not credible and blamed Russian interference.

“Looks like they’re being naughty,” he said. “They don’t want us to have a smooth, fair and accurate election.”

The FBI also warned that two viral videos purporting to belong to the agency urging Americans to “vote remotely” due to terrorist threats and voter fraud are “not real.”

Speaking from Palm Beach, where he cast his ballot, Trump said there would be “no violence” after the result and promised to leave the contest to Ms. Harris if she wins and “if it’s a fair election.”

“If I lose an election, if it’s a fair election, I’ll be the first to admit it,” he said. “And… I think that was fair.”

Trump’s former lawyer Rudy Giuliani told The Telegraph he had seen no signs of fraud but added: “I know anything is possible with crooked Democrats.”

Trump also said he is running the best campaign of his life and is confident of victory. He said he would not stand for a fourth time if he lost, leaving politics “sad and very satisfied”.

Asked whether he would call for calm among his supporters if he loses, Trump replied: “I definitely do not want violence. Of course there will be no violence; my supporters are not violent people.”
