US Presidential candidate Donald Trump has suggested the country's vice-president Joe Biden has a "long history of grabbing, kissing and groping women" as the sexism row surrounding the billionaire politician drags on.
Trump retweeted a message from a radio host called Mark Simone, advertising a video about the alleged sexist behaviour of Biden, who has twice been elected vice-president under Barack Obama.
In a rapid-fire string of tweets, Trump also said: "Can't believe these totally phoney stories, 100% made up by women (many already proven false) and pushed big time by press, have impact!"
He also retweeted a message from an account called Prison Planet, claiming a woman who accused him of sexual assault praised him as recently as April.
Trump has been battling a string of sexism allegations over recent weeks. Former contestants of his reality TV show The Apprentice came out with claims that he belittled and harassed them during filming, before the appearance of leaked footage which appeared to show him claiming that he could grab women by their genitalia with impunity.
The controversy appears to have hurt Trump's standing with US voters, with the latest polls suggesting his Democratic rival Hillary Clinton has a substantial lead in the US presidential election race.
Trump has, in turn, criticised Clinton's husband Bill for a string of alleged sexism offences, and attacked Hillary Clinton for defending a convicted rapist during her legal career. He has also suggested his leaked comments about groping women were nothing more than "locker-room talk."
