Donald Trump has been caught on tape making lewd comments about kissing and trying to have sex with women.
Footage, recorded in 2005 and since obtained by the Washington Post, shows the Republican presidential nominee boasting about his past liaisons, saying: “When you’re a star, they let you do it”.
“Grab them by the p***y - you can do anything," he adds.
The comments were made as Mr Trump - who at the time had recently married his current wife Melania - travelled in a bus with TV personality Billy Bush to film a cameo appearance on a soap opera.
Discussing a failed attempt to seduce a woman, the businessman says: “I moved on her and I failed. I’ll admit it. I did try and f*** her. She was married.
"And I moved on her very heavily. In fact, I took her out furniture shopping. She wanted to get some furniture. I said,‘I’ll show you where they have some nice furniture.’
“I moved on her like a b****, 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 t*** and everything. She’s totally changed her look.”
When Mr Trump sees an actress waiting to escort him on set, he says: “Whoa! I’ve gotta use some tic tacs, just in case I start kissing her."
He adds: “You know I’m automatically attracted to beautiful - I just start kissing them. It’s like a magnet. Just kiss. I don’t even wait.”
The recording emerged at a time when Mr Trump is desperate to win the votes of white college-educated women.
He has also threatened to discuss Bill Clinton's past infidelities, describing the former president in a recent interview as "the single greatest abuser of women in the history of politics".
Responding to the recording, Mr Trump apologised for what he called "locker room banter", but accused Mr Clinton of saying "far worse to me on the golf course".
“This was locker room banter, a private conversation that took place many years ago," Mr Trump said in a statement.
"Bill Clinton has said far worse to me on the golf course - not even close. I apologise if anyone was offended."
A spokesperson for the Hillary Clinton campaign said: "This is horrific. We cannot allow this man to become president."
Tim Kaine, Clinton's running mate, said Mr Trump's comments "make me me sick to my stomach".
"This is behaviour that’s just outrageous....I should be, I should be surprised and shocked. I’m sad to say that I’m not."
Our Washington Correspondent Robert Moore said the recording raised the stakes for Sunday's second presidential debate, adding: "How much more ammo does Hillary need?"
