A day after Donald Trump and Hillary Clinton debated a second time, deep cracks in the Republican Party are widening. The party's nominee is sharply criticizing House Speaker Paul Ryan. And that comes as Ryan tells colleagues he no longer will defend Trump — advising them to "Do what's best for you in your district" in order to protect the GOP majority in Congress. Josh Robin reports.

At least 60 million people tuned in — and for one influential viewer, Donald Trump apparently didn't do well enough.

Fearing Trump could drag Republicans into the Congressional minority, the House Speaker is all but conceding Hillary Clinton will win.

He's privately telling Republicans in vulnerable districts to run as a check on her presidency.

Donald Trump didn't mention Ryan at a Pennsylvania rally, letting his Twitter do the talking.

It's this 2005 tape tipping Trump into full radioactivity.

He lewdly boasts his celebrity status allows him to fondle women without their permission, and it's apparently not the only damning recording out there.

"If they want to release more tapes saying inappropriate things, we'll continue to talk about Bill and Hillary Clinton doing inappropriate things," Trump said at a Rally Monday.

Hometown crowd notwithstanding, Trump also likely isn't helping his appeal by praising Steelers Quarterback Ben Roethisberger, who was suspended for a pair of sexual assault allegations that resulted in no charges.

The self-professed billionaire also turned heads with this comment:

"And I consider myself in a certain way to be a blue collar worker," the real-estate developer said.

While House Republicans may be fleeing Trump, the Republican National Committee is said to be standing with him. That split is sowing confusion about how the GOP spends money in the remaining four weeks.

Enter Hillary Clinton, organizing early voting, and stressing the video is but one example of sick behavior.

"Here's a man who has insulted not just women, but African-Americans, Latinos, people with disabilities, Muslims, P.O.W.S."

Clinton faces her own embarrassment amid new WikiLeaks documents, showing her struggling to outpace primary rival Bernie Sanders.
