Donald Trump on Saturday vowed to "never" drop out of the presidential race as a growing chorus of Republicans urged him to do exactly that after sexually aggressive remarks he made in 2005 surfaced a day earlier.
Trump's defiance came as his own running mate, Indiana Gov. Mike Pence, said he was "offended" by Trump's remarks and canceled plans to represent him at a political event on Saturday. Meanwhile, the third-most powerful Senate Republican, John Thune, a member of Senate Majority Leader Mitch McConnell's inner circle, called on Trump to "withdraw" and let Pence top the Republican ticket just a month from Election Day.
"I'd never withdraw. I've never withdrawn in my life," Trump told The Washington Post Saturday morning. "No, I'm not quitting. I have tremendous support."
He also told The Wall Street Journal there is "zero chance I'll quit."
The comments suggested that Trump was eager to fully turn away from the lewd and sexually aggressive terms he used to describe women in the 2005 conversation and instead pivot toward his political opponents, whoever they may be.
"They're not going to make me quit, and they can't make me quit," Trump told the Post.
The interviews took place less than 24 hours after previously unaired footage surfaced of Trump bragging about being able to grope women and trying to have sex with a married woman during a 2005 taping for "Access Hollywood."
In that timespan, Republicans have quickly condemned Trump for the comment many of them have deemed "inexcusable" and "indefensible," prompting Trump to issue his first-ever apology of his nearly 16-month campaign.
But Trump also signaled a willingness to fight in the 90-second video statement he posted online just after midnight on Saturday, quickly turning from apologizing to attacking Democratic nominee Hillary Clinton for her husband's sex scandals.
But the apology did not quell the firestorm.
Several Republicans, including Sens. Mike Crapo of Idaho and Kelly Ayotte of New Hampshire, formally pulled their support of Trump on Saturday morning.
Pence 'cannot defend' remarks
And after a campaign source told CNN that Pence decided not to attend the Wisconsin political event hosted by House Speaker Paul Ryan, Pence released a statement explaining that he was "offended" by Trump's remarks. He also noted he is looking "forward to the opportunity he has to show what is in his heart" at the debate on Sunday.
"As a husband and father, I was offended by the words and actions described by Donald Trump in the 11-year-old video released yesterday," Pence said. "I do not condone his remarks and cannot defend them. I am grateful that he has expressed remorse and apologized to the American people. We pray for his family and look forward to the opportunity he has to show what is in his heart when he goes before the nation tomorrow night."
"Wisconsin is off" for Pence, a campaign source told CNN earlier Saturday, adding that the decision was made this morning.
The source gave no reason for the cancellation, but the Trump campaign had announced Friday evening that Pence would attend the event in Trump's stead after Ryan said he was "sickened" by Trump's comments and announced Trump would no longer attend the event.
Multiple sources told CNN that Trump was asked not to come by Ryan, and one source said the message was delivered via intermediaries.
And while the real estate magnate was slated to spend Saturday focusing on debate prep, Trump instead spent Saturday morning boldly countering the growing calls for him to drop out of the presidential race, with some Republicans suggesting Trump should step aside and allow Pence to top the Republican ticket. With just one month to Election Day and as early voting has already begun in some states, replacing the Republican nominee would be a near-impossible task.
Ready to fight back
Trump indicated he will head into the debate prepared to fight Clinton by raising the marital infidelities of her husband former President Bill Clinton -- a shift since Trump said as recently as Thursday night he would not raise the issue in Sunday's debate.
And Trump argued to the Post that he will be able to weather the comments that have come back to haunt him in part because Clinton, the Democratic nominee, is "so bad" and "so flawed as a candidate."
"Running against her, I can't say it'd be the same if I ran against someone else, but running against her makes it a lot easier, that's for sure," Trump said in the Saturday morning interview.
Trump also told both the Post and the Journal that he is considering delivering remarks Saturday evening to encourage his supporters and address the controversy.
And he also said of the 2005 comments that "people get it. They get life."
Pressed a final time by the Post about the possibility he could quit the race, Trump firmly shut the door on that option.
"Zero chance. I've never quit in my life," Trump said. "I can give you my word that I'm never leaving."
