Donald Trump says he will not quit over video

US presidential candidate Donald Trump has said he will not withdraw from the race in phone interviews with US media.

Mr Trump has been under pressure after a tape of him making lewd sexual comments and bragging about groping and kissing women emerged on Friday.

He told the Wall Street Journal there was "zero chance I'll quit" and he was getting "unbelievable" support.

Top Republicans condemned his remarks in the video. Mr Trump's election rival Hillary Clinton called them "horrific".

His running mate Mike Pence said he was "offended" by Mr Trump's video but grateful he had expressed remorse and apologised to the American people.

"We pray for his family" he said in a statement.

The candidate released a video statement apologising for the comments.

After some Republican lawmakers called on Mr Trump to step down as candidate, the billionaire told the Washington Post later on Saturday:

"I'd never withdraw. I've never withdrawn in my life."

"Certainly has been an interesting 24 hours!" Mr Trump wrote on Twitter on Saturday.

Mr Trump's 2005 comments, posted by the Washington Post, overshadowed the release of transcripts of Mrs Clinton's speeches to private events, by the whistle-blowing site Wikileaks.

The candidate had married his third wife Melania a few months before the recording. She said on Saturday: "I hope people will accept his apology, as I have, and focus on the important issues facing our nation and the world."

On Saturday New Hampshire Senator Kelly Ayotte joined the long list of Republican members of Congress who have said they will not vote for Mr Trump.

"I cannot and will not support a candidate for president who brags about degrading and assaulting women," she said in a statement.

Ms Ayotte - who faces a competitive race for re-election - said she would not vote for Mrs Clinton but instead would "write in" Mr Pence, on her ballot paper.

Reports in the US media suggest that Mr Pence no longer plans to attend a campaign event in Wisconsin alongside House Speaker Paul Ryan.

Mr Ryan - the most senior elected Republican in the US - had originally invited Mr Trump to the event but rescinded his invitation, saying he was "sickened" by what he had heard. Mr Pence was due to go in his running mate's place.

Senators Mike Crapo of Idaho, Ben Sasse of Nebraska, Mike Lee of Utah, Dan Sullivan of Alaska and John Thune of South Dakota were among the elected Republicans calling on Mr Trump to abandon his candidacy.
