SAN FRANCISCO — Democratic presidential nominee Hillary Clinton called the testimonials of women who say they were sexually harassed or abused by Republican Donald Trump “disturbing” on Thursday, as she lamented the negative tone of the election.

“It makes you want to turn off the news. It makes you want to unplug the Internet, or just look at cat GIFs,” Clinton told a group of donors at a fundraising party. “I get it,” she said, adding that she herself has recently “watched a lot of cats do a lot of weird and interesting things.”

She joked: “But we have a job to do and it’ll be good for people and for cats.”

The joke about cat videos was a light moment in an otherwise sober discussion of the election tone 26 days before the election. It was her most direct reaction to date to a stream of accusations from women who said that Trump groped them or otherwise behaved inappropriately.

“The whole world has heard Trump brag about how he mistreats women. And the disturbing stories just keep coming, but it’s more than just the way he degrades women, as horrible as that is,” Clinton said. “He has attacked immigrants, African Americans, Latinos, people with disabilities, POWs, Muslims, and our military, which he’s called a disaster. There's hardly any part of America that he’s not targeted.”

Earlier, Clinton urged volunteers and staff at a campaign office here to look past the current debate.

“We cannot let this pessimism, this dark and divisive and dangerous vision of America, take hold in anybody's heart,” Clinton said. “We have to keep lifting up this campaign.”

“I really want all of our people, but especially our young people, and our children to know that America is great because America is good,” Clinton said.

“I feel this responsibility especially deeply. You know, if I were running against any Republican, I would be working hard and I would be asking for your help,” Clinton said. “But this is such an election between two very different visions, views, and sets of values. And that’s why the stakes are so high. Because we know we've already learned who Donald Trump is. What we have to prove in this election is who we are, and what we stand for and what we believe in.”

Also Thursday, Clinton campaign manager Robby Mook told reporters that Trump's accusations and the current tenor of the election will not affect Clinton's strategy.

“We will continue to express our concern at the pattern of behavior by Donald Trump,” Mook said during a conference call.

Mook said that mail-in ballot requests in key states including Florida and North Carolina augur well for Democrats. He said initial indications from early in-person voting are also positive for his side.

“We are seeing really strong numbers,” Mook said. “All the data that we’re seeing is reinforcing that this will be the biggest election and biggest turnout in our history.”
