Late Friday night, Donald Trump issued a video apology after his vulgar comments about women from a 2005 interview leaked.
"I've never said I'm a flawless person, nor pretended to be someone I'm not", Trump said.
"I've said some foolish things", Trump said in a taped apology posted on his Facebook page.
In a 2005 conversation with Access Hollywood host Billy Bush, Trump declared he could "grab women by the pussy" because he was famous.
"I am sickened by what I heard today", Ryan said.
Trump, known for his unconventional and controversial speaking style, has made a series of gaffes in his campaign but the graphic nature of the clip would hurt his standing among women, independents, and wavering Republicans, said David Yepsen, director of the Paul Simon Public Policy Institute at Southern Illinois University. Ryan revoked an invitation for Trump to appear at a GOP event Saturday in Wisconsin.
"The fact that he's not just describing the attractiveness of a woman, he's not just sort of leering at a woman".
Meanwhile, the Republican Representative for Utah, Jason Chaffetz, told CNN that he was retracting his endorsement because he would not be able to look his 15-year-old daughter in the eye if he voted for Trump.
The two previous Republican presidential nominees also condemned Trump's comments.
Trump's 90-second statement capped a jarring day that threatened to sink his presidential campaign and sent Republicans into a panic with early voting well underway in several states and a little more than a month until Election Day.
But the provocative billionaire quickly and defiantly pivoted from his own crisis to attack former president Bill Clinton, saying Hillary's husband "abused" women.

"This is horrific. We can not allow this man to become president", the tweet reads, with the Post's story linked below. "It is just sad and embarrassing that man who is now the nominee of a major party for President could display such a disgusting attitude toward women".
"You know, I'm automatically attracted to beautiful (women) - I just start kissing them", Trump said at one point, apparently unaware he was being taped. "It's like a magnet". I am automatically attracted to handsome (women).
Trump was forced to apologise after the video surfaced online and, therefore, posted a video saying: "I never said that I am a ideal person". You can do anything. He also said he would "grab them by the p--y", referring to women he was attracted to. "See you at the debate on Sunday", Trump said in his statement. He's been accused of making unwanted sexual advances toward women in the past.
"I moved on her and I failed". Asked in a debate with her Democratic opponent if she considered Trump a role model for children, she said "absolutely". In the video, Trump is heard describing attempts to have sex with a married woman.
He apologized in a video statement released by his campaign after midnight early Saturday morning. "This is nothing more than a distraction from the important issues we're facing today".
"We are working to evaluate the appropriate messaging going forward", said RNC chief strategist Sean Spicer. We are losing our jobs, we are less safe than we were 8 years ago and Washington is broken. Since his feeble showing in the first debate with Hillary Clinton, he has lost crucial ground both in national polls and in nearly every swing state.
He and Trump spoke as the future Republican presidential candidate prepared to tape a cameo on the daytime soap "Days of Our Lives".
A number of Republicans, meanwhile, said the comments may well end whatever chance Trump had to prevail in the November 8 election.
Fahrenthold, who has been reporting for months on Trump's charitable donations and the Trump Foundation, was contacted around 11 a.m. on Friday by a source who told him about the footage, according to a Post story about how he got this scoop. "I'm very sorry", he said.
