Donald Trump lost the support of a number of Republicans after the release of a 2005 audio recording of his vulgar comments about women.

While these Republican leaders say they won't vote for Trump, most won't vote for Democrat Hillary Clinton either. Many have called for Trump to step down and let his running mate Mike Pence lead the ticket.

Here's a look at the party leaders who have recently vowed not to support Trump in the election, as well as some who already said they wouldn't vote for Trump before his lewd remarks were made public.

John McCain

"Donald Trump's behavior 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," Arizona Sen. John McCain said in a statement on Oct. 8, 2016. "Cindy and I will not vote for Donald Trump. I have never voted for a Democratic presidential candidate and we will not vote for Hillary Clinton. We will write in the name of some good conservative Republican who is qualified to be President." (Credit: Getty Images / Chip Somodevilla)

John Kasich

"Donald Trump is a man I cannot and should not support," Ohio Gov. John Kasich said in a statement on Oct. 8, 2016. "The actions of the last day are disgusting, but that's not why I reached this decision, it has been an accumulation of his words and actions that many have been warning about. I will not vote for a nominee who has behaved in a manner that reflects so poorly on our country. Our country deserves better."

Jason Chaffetz

"My wife, Julia, and I, we got a 15-year-old daughter. Do you think I can look her in the eye and tell her that I endorsed Donald Trump for president when he acts like this, and his apology? That was no apology, that was an apology for getting caught," Utah Rep. Jason Chaffetz said on CNN on Oct. 7, 2016. "So I'm not going to put my good name and reputation and my family behind Donald Trump for president when he acts like this, I just can't do it." (Credit: Getty Images / Alex Wong)

Carly Fiorina

"Donald Trump does not represent me or my party. I understand the responsibility of Republicans to support their nominee. Our nominee has weighty responsibilities as well. Donald Trump has manifestly failed in these responsibilities," Carly Fiorina said in a statement on Facebook on Oct. 8, 2016. "I have traveled the country for years warning Americans that Hillary Clinton is unfit to be President. We must have a conservative in the White House to restore accountability, opportunity and security. For the sake of our Constitution and the rule of law, we must defeat Hillary Clinton. Today I ask Donald Trump to step aside and for the RNC to replace him with Gov. Mike Pence." (Credit: Getty Images / Bob Levey)

Kelly Ayotte

"I will not be voting for Donald Trump or Hillary Clinton and instead will be writing in Governor Pence for president on Election Day," New Hampshire Sen. Kelly Ayotte said Saturday, Oct. 8, 2016, in a statement. "I wanted to be able to support my party's nominee, chosen by the people, because I feel strongly that we need a change in direction for our country. However, I'm a mom and an American first, and I cannot and will not support a candidate for president who brags about degrading and assaulting women." (Credit: Getty Images / Chip Somodevilla)

Mike Crapo

"I have reached the decision that I can no longer endorse Donald Trump. This is not a decision that I have reached lightly, but his pattern of behavior has left me no choice," Idaho Sen. Mike Crapo said in a statement on Oct. 8, 2016. "Trump's most recent excuse of 'locker room talk' is completely unacceptable and is inconsistent with protecting women from abusive, disparaging treatment.

"I urge Donald Trump to step aside and allow the Republican party to put forward a conservative candidate like Mike Pence who can defeat Hillary Clinton."

Martha Roby

"Donald Trump's behavior makes him unacceptable as a candidate for president, and I won't vote for him," Alabama Rep. Martha Roby said in a statement on Oct. 8, 2016. "I thought supporting the nominee was the best thing for our country and our party. Now, it is abundantly clear that the best thing for our country and our party is for Trump to step aside and allow a responsible, respectable Republican to lead the ticket. Hillary Clinton must not be president, but, with Trump leading the ticket, she will be."

"If Donald Trump wishes to defeat Hillary Clinton, he should do the only thing that will allow us to do so - step aside, and allow Mike Pence to be the Republican party's nominee.

Lisa Murkowski said in a statement on Oct. 8, 2016. "I have always supported the Republican presidential nominee and I had hoped to do the same in 2016. The video that surfaced yesterday further revealed his true character. He not only objectified women, he bragged about preying upon them. I cannot and will not support Donald Trump for President - he has forfeited the right to be our party's nominee. He must step aside." (Credit: Getty Images / Alex Wong)

Dan Sullivan

"I've worked to encourage men to choose respect and change the culture of abuse against women and children, which is at epidemic levels in Alaska and many parts of the country. We need national leaders who can lead by example on this critical issue. The reprehensible revelations about Donald Trump have shown that he can't," Alaska Sen. Dan Sullivan said in a statement on Oct. 8, 2016. "Therefore, I am withdrawing my support for his candidacy."

"I cannot and will not support Hillary Clinton. She and her husband have their own sordid history of abuse of women," he added. Sullivan said he will campaign for other Republican candidates across the country. "Keeping Republicans in the Senate majority is critical to the economic and national security of Alaska and America. As for the White House, Donald Trump should step aside. I will support Governor Mike Pence for President," he said.
