Republican candidate Donald Trump has responded to a 2005 video showing him making obscene comments about women.
In the video, posted by the Washington Post, Mr Trump is heard telling TV host Billy Bush “you can do anything” to women “when you’re a star”.
The New York businessman bragged about trying to have sex with a married woman as well as kissing and groping others.
Mr Trump quickly dismissed it as “locker room banter” and added, “Bill Clinton has said far worse to me”.
After the video became public, senior Republicans condemned Mr Trump’s comments.
Mr Trump said that his vice-presidential running mate Mike Pence would represent him at the Wisconsin event.
Another senior Republican, John McCain, said there were “no excuses for Donald Trump’s offensive and demeaning comments”.
The video has emerged two days before Mr Trump takes part in the second presidential debate with his Democratic opponent Hillary Clinton.
The two candidates will be in St Louis for the televised encounter, with polling day only a month away.
The clip was part of unaired footage of an Access Hollywood segment ahead of Mr Trump’s appearance on the soap opera Days of Our Lives.
“I moved on her and I failed. I’ll admit it,” Trump is heard saying. “She was married. And I moved on her very heavily.”
“I moved on her like a bitch, but I couldn’t get there. And she was married. Then all of a sudden I see her, she’s now got the big phony tits and everything. She’s totally changed her look.”
Later in the conversation, he told Bush he is “automatically attracted to beautiful” women and often tries to kiss them.
“I just start kissing them,” he said. “I don’t even wait. And when you’re a star they let you do it. You can do anything.”
“Grab them by the pussy,” Mr Trump says. “You can do anything.”
Mr Trump issued a statement shortly after the footage was leaked.
“This was locker room banter, a private conversation that took place many years ago,” the statement read.
“Bill Clinton has said far worse to me on the golf course – not even close. I apologise if anyone was offended.”
For his part, Mr Bush said he was “embarrassed and ashamed” at the contents of the video.
“It’s no excuse, but this happened 11 years ago – I was younger, less mature, and acted foolishly in playing along. I’m very sorry.”
In a recently released photo obtained by the National Daily Enquirer Sunday Review, a naked Donald Trump is in a hotel room sitting on the edge of a bed. Next to him is Rosie O’Donnell’s sister Marta, also naked and holding a battle axe!
What was this stuff about ‘the Donald’ having disdain for fat women?
