Entertainment Tonight host Nancy O'Dell, external, who was identified as the Nancy in the 2005 video, has released the following statement.

"Politics aside, I’m saddened that these comments still exist in our society at all. When I heard the comments yesterday, it was disappointing to hear such objectification of women. The conversation needs to change because no female, no person, should be the subject of such crass comments, whether or not cameras are rolling. Everyone deserves respect no matter the setting or gender. As a woman who has worked very hard to establish her career, and as a mom, I feel I must speak out with the hope that as a society we will always strive to be better."

Arizona Republican senator and 2008 presidential nominee John McCain says he can no longer support Trump because of his "boasts about sexual assaults" and "demeaning" comments about women.

"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. Cindy, with her strong background in human rights and respect for women, fully agrees with me in this."

McCain said he and his wife will not vote for Hillary Clinton and will instead write in "some good conservative Republican who is qualified to be president". 

A write-in would see a candidate whose name does not appear on the ballot voted for anyway - by writing in the person's name. However, there has never been a winning write-in campaign in a US presidential contest.   

The makers of the sweets Trump said he uses to freshen his breath before meeting women are not happy to have been mentioned in the video. 

Vice President Joe Biden has joined the chorus of people voicing their anger at Donald Trump's comments in the video released yesterday.

CNN have been digging into the archives, external of Donald Trump's many interviews with US radio shock-jock Howard Stern and unearthed a long list of crude remarks about women. 

In a September 2004 interview, Stern talks about Trump's daughter Ivanka, asking if he can call her "a piece of ass" to which Trump replies: "Yeah."

In another interview two years later, Stern asks if Ivanka has had breast implants because she "looks more voluptuous than ever". Trump insists she hasn't, saying: "She's actually always been very voluptuous."

Our clever BBC colleagues have put together a very nifty long-form interactive on the life of Donald Trump.

From his mock-Tudor home in Queens, to military academy, to reality television and the Republican primaries...

Shaun McCutcheon, who was a delegate for Alabama at the Republican convention, said Trump's comments weren't a big surprise because "we know he was a sort of playboy", and he is still going to vote for Trump.

"It is not acceptable - he can't behave that way in office or he'll have to be impeached," he told the BBC.

"I've heard worse in locker rooms - it is locker room talk between men. It was supposed to be a private conversation - that's no excuse but that's what it was.

"I think he did the right thing to apologise and not try to defend it.”

Some people are saying the media isn't going far enough in describing Trump's behaviour. 

Amanda Pustilnik, a professor of law at the University of Maryland School of Law, says Trump's comments aren't "lewd comments", "sex talk" or "harassment" - rather "in his statements he confessed to multiple counts of sexual battery".

Nor are Trump's statements "bragging", she argues, pointing out Trump said he grabs women by the genitals.

Prior to this latest scandal for Donald Trump, his campaign team were hoping a rumoured Wikileaks release would derail Hillary Clinton's bid to be president. 

That release came late last night when Wikileaks published what they said were transcripts of private speeches given by Clinton. 

The BBC's Anthony Zurcher says they provide "yet more evidence that Clinton is pro-open-trade and sympathetic to Wall Street interests, despite her protestations otherwise".

"They also reveal a decidedly middle-of-the-road, pragmatic political attitude that won't sit well with the populist wing of her own party."

Earlier this month, the BBC met a group of female Trump supporters in Beverly Hills who call themselves The Trumpettes, to find out why they are voting for the Republican candidate.

When Linda was asked today if her mind had been changed at all by the tape of him making lewd sexual comments emerged, she said it hadn't.

"Most guys have locker room language," she told the BBC. "Hillary Clinton is corruption personified. She uses the poor and naive public. She absolutely should never become president. She totally uses Saul Alinsky's socialist agenda, which defiles our constitution. 

"Trump may have bad language but so does Hillary. Trump wants to rebuild America. Hillary Clinton just uses government to enhance her pockets."

Former Minnesota Governor Tim Pawlenty has joined the growing list of Republicans who have withdrawn their support for Donald Trump in the last 24 hours. 

In a statement emailed to reporters, he said Trump is "unwilling or unable to demonstrate even the most basic level of discipline, character and judgment necessary to lead our great nation".

"He is unsound, uninformed, unhinged and unfit to be president of the United States, and I am withdrawing my support for him."

The Republican National Committee appears to have at least temporarily halted the operations of some of the "Victory" programme that is devoted to electing Donald Trump, Politico reports, external.

In an email from the RNC to a victory programme mail vendor, with the subject line "Hold on all projects", the committee asked the vendor to "put a hold" on mail production, it says.

"Please put a hold/stop on all mail projects right now. If something is in production or print it needs to stop. Will update you when to proceed," Lauren Toomey, a staffer in the RNC's political department, wrote in an email that was obtained by Politico.

Neither Toomey nor Rick Wiley, a top RNC official who was cc'd on the email, responded to requests for comment.

Republican fundraising chief Spencer Zwick says he's been fielding calls from donors who "want help putting money together to fund a new person to be the GOP nominee" - although he didn't identify who this "new person" might be.

A write-in campaign - which would see a candidate whose name does not appear on the ballot voted for anyway by writing in the person's name - relying on social media could actually work, he tells AP.

There's never been a winning write-in campaign in a US presidential contest. Many states do not allow write-in candidates for president, while others require them to register.

Early voting is also already underway in several states, which presents another issue. 

Can Republicans really dump Trump?

Despite a slew of Republicans publicly calling on Trump to quit, he insists none of them have picked up the phone to talk to him. 

"I haven’t heard from anyone saying I should drop out, and that would never happen, never happen," he told the New York Times, external earlier today. 

He added: "Oh yeah, we can win — we will win. We have tremendous support. I think a lot of people underestimate how loyal my supporters are."

The architect of Britain's vote to leave the European Union, Nigel Farage, has been speaking to Fox News about the latest Trump furore.

He described it as "alpha-male boasting" but advised Trump to hold his hands up at Sunday's debate.

"It's not good but there's a whole host of stories coming out about Hillary Clinton, not to mention Bill, about sexual impropriety."
