US Presdiential candidate Donald Trump has vowed he will never drop out of the race after tapes of him making lewd comments emerged.
He told the Wall Street Journal there was "zero chance I'll quit" and he was getting "unbelievable" support.
The media and establishment want me out of the race so badly - I WILL NEVER DROP OUT OF THE RACE, WILL NEVER LET MY SUPPORTERS DOWN! #MAGA— Donald J. Trump (@realDonaldTrump) October 8, 2016
Since the tape emerged, at least 10 Republican senators have either said they will not be voting for the Republican candidate in the general election in 30 days' time, or have called for him to stand aside.
The latest to join them is former Republican presidential candidate John McCain, who said Mr Trump's comments "make it impossible to continue to offer even conditional support for his candidacy".
And former Secretary of State Condoleezza Rice said: "Enough! Donald Trump should not be President. He should withdraw."
Mr Trump's election rival Hillary Clinton called the comments "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.
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Mr Ryan - the most senior elected Republican in the US - had originally invited Mr Trump to the event but rescinded his invitation, saying he was "sickened" by what he had heard.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.
Former Republican California Governor Arnold Schwarzenegger also said he would not be voting for the Republican candidate.
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.
The second TV debate between Mr Trump and Mrs Clinton will take place on Sunday evening (US time) in St Louis.
Mr Trump recently said he would not bring up stories about Bill Clinton's infidelities in the debate, after previously threatening to do so.
But in his video apology, he attacked the former president directly:
"Bill Clinton has actually abused women, and Hillary has bullied, attacked and shamed his victims.
"We'll discuss this in the coming days," he said. "See you at the debate on Sunday."
