“There are no excuses for Donald Trump’s offensive and demeaning comments," the Arizona senator said in a statement. "No woman should ever be victimized by this kind of inappropriate behavior. He alone bears the burden of his conduct and alone should suffer the consequences."

McCain's statement is the latest backlash from congressional Republicans against the embattled nominee, after The Washington Post published audio of the businessman making explicit comments about trying to have sex with women, which were caught on a hot mic in 2005.

Trump issued a half-apology, saying the comments were private "locker-room banter" and "I apologize if anyone was offended."

"McCain has stood by Trump after attacking Khan family, veterans, women & immigrants. We know where McCain stands -- with Trump," she said on Twitter. "Trump's comment proves: In the past McCain took the mic from those who didn't deserve it. In 2016, he supports them for president."

But GOP senators have so far refused, while also disavowing the comments.

McCain — like other Senate Republicans — has walked a fine line on Trump. He frequently refuses to answer questions from reporters in the Capitol about his party's nominee, but has also made it clear that he will support him in the November election.

He also recently defended Trump after Democrats and some pundits accused the GOP nominee of saying veterans who suffer from post-traumatic stress disorder (PTSD) are weak-minded.

"The bias that is in the media,” McCain told the Arizona Daily Star's editorial board on Tuesday. “What he is saying is that some people, for whatever reason, and we really don’t understand why, suffer from PTSD, and others don’t.”

Democrats need to win back five seats — or four if they also retain the White House — to win back the Senate and believe Trump at the top of the ticket will help them by dragging down GOP congressional candidates.

McCain has been able to pull away from Trump in the state, leading Kirkpatrick by 16 percentage points even though Trump and Clinton are in a dead heat, according to Real Clear Politics.
