US Elections

At least a dozen Republicans have said they will not be voting for him, since the comments emerged on Friday.

Mr Trump says he will never drop out of the race to be president and will never let his supporters down.

He has been under pressure after a tape from 2005 of him bragging about groping and kissing women was broadcast.

'Enough!'

The latest to withdraw their support are former Republican presidential candidate John McCain and former Secretary of State Condoleezza Rice.

Many in the GOP are reeling from shock, revulsion and utter confusion about what to do next after a video surfaced Friday of Donald Trump talking about women in crude and aggressive sexual terms.

Donald Trump engaged in crude and demeaning conversations about women over a 17-year-period with radio shock-jock Howard Stern, according to a review by CNN's KFile of hours of newly uncovered audio.

Among the topics Trump discussed: his daughter Ivanka's physique, having sex with women on their menstrual cycles, threesomes, and checking out of a relationship with women after they turn 35.

CNN's KFILE has now uncovered two more Playboy videos in which Trump makes an appearance, including one in which he is depicted photographing fully clothed models with a Polaroid camera and conducting an interview with a potential Playmate.

In that video — a 1994 VHS tape obtained by CNN titled "Playboy Centerfold" — Trump takes part in Playboy magazine's search for its 40th anniversary Playmate.

"She's nasty," Trump told The New York Times in an interview published Friday night, "but I can be nastier than she ever can be."

The comments were part of a wide ranging interview in which Trump also touched upon his marriages, his recent late-night Twitter rant and his performance at the first presidential debate.

The 58-year-old star took to Twitter to post a racy snap with the caption “[I’m] voting naked with Katy Perry!! Vote for Hillary. She's the Best we got! Nude Voting series # 1.”

She also stood up for Rosie O’Donnell, who has been in a heated feud with republican candidate Donald Trump.

Madonna’s nude snap came on the heels of Perry’s “Funny or Die” video that showed the “Rise” singer heading to polls and stripping down.

Now, 20 years later, she is back in the headlines.

Ms Machado claims she was called "Miss Piggy" by Donald Trump, the Republican candidate for the White House who owned the beauty pageant when she won it.

The remarks were made, the Venezuela-born model says, after she put on some weight following her win.

How did it come up?

The issue was brought up by Hillary Clinton, the Democratic presidential nominee, during Monday's televised debate with Mr Trump. She was making a point about her rival's remarks about women.

That drubbing is similar to Mitt Romney's dominant performance over President Barack Obama in the first 2012 presidential debate.

Voters who watched said Clinton expressed her views more clearly than Trump and had a better understanding of the issues by a margin of more than 2-to-1. Clinton also was seen as having done a better job addressing concerns voters might have about her potential presidency by a 57% to 35% margin, and as the stronger leader by a 56% to 39% margin.

Perhaps we should call it "Smackdown at the Mack," since it is being held at the Hofstra University's David S. Mack Sports and Exhibition Complex on New York's Long Island.

So how should you watch this D-Day of Debates? We have some tips for you:

What time does it start?

When Hillary Clinton takes the stage at the first presidential debate, she will make history. Over the past few months the level of scrutiny faced by the first female candidate for president of the United States has ramped up: her policies, her emails, her relationships have been critiqued, dissected and analysed. And so have her clothes.
