Donald Trump remains defiant in the wake of a video which emerged of him making obscene comments about women.

Trump is facing a huge backlash over the video in which he boasted about kissing women whether they wanted him to or not.

As both Republicans and Democrats called for Trump to step down, he decided that attack was the best form of defence and issued a string of damning tweets about his opponents.

He has highlighted never-proved rape allegations against his rival Hillary Clinton’s husband Bill by tweeting a link to an interview with the woman who accused Bill of rape.

Her lawsuit was dismissed in 2001. No criminal charges were ever brought and Bill has always denied the allegations.

Hillary Clinton’s running mate Tim Kaine said it was Trump who ought to be taking stock of how he spoke about and treated women. Kaine said the audio recording showed “a pattern” of sexual assault by Trump.

He added: “There’s kind of a piece of the jigsaw puzzle missing in Donald Trump where he does not look at women and consider them as equal to himself.”

Since the video emerged, nearly 40 senior Republicans have said they have had no choice but to withdraw their support for Trump.

Senator John McCain, who was Republican nominee himself in 2008, said: “Donald Trump’s behaviour this week, concluding with the disclosure of his demeaning comments about women and his boasts about sexual assaults make it impossible to continue to offer even conditional support for his candidacy.”

Meanwhile Trump’s own running mate Mike Pence moved to remove himself from the comments. He said he could neither condone nor defend Trump’s words, adding that he was praying for Trump’s family.

Terminator actor and former California Governor Arnold Schwarzenegger has publically said he will not be voting for Trump.

However support has come from former New York mayor Rudy Giuliani who said: “Men at times talk like that.”

Support also came from the UK where interim UK Independence Party leader Nigel Farage said that while the remarks were “ugly,” they were something “if we are being honest that men do”.

Trump has issued an apology for what he said, admitting that he is not perfect and he has done and said things he regrets, including the words on the video.

Accusing Bill Clinton of doing far worse, he added: “Anyone who knows me knows these words don’t reflect who I am. I said it, I was wrong and I apologise.”
