Hillary Clinton has given her most political speech since her U.S. presidential election defeat in November 2016, calling on her audience to “Resist, insist, persist, enlist.”

Speaking at a diversity conference in San Francisco, Clinton encouraged attendees to “resist actions that go against our values as Americans,” and said she would “be right there with you every step of the way,”

Clinton also slammed the Republicans’ failed attempts at healthcare reform, calling a mooted replacement for the Affordable Care Act, which the party was forced to abandon last week, “a disastrous bill.”

In particular, she attacked the right’s attempts to take away protections for women. “Take away maternity care?” Clinton said. “Who do these people talk to?”

“Advancing the rights and opportunities of women and girls is the great unfinished business of the 21st century,” she said, adding that women’s representation in Washington is “the lowest it’s been in a generation.”

She also said Tuesday reporter April Ryan was “patronized” by White House press secretary Sean Spicer and called FOX News host Bill O’Reilly “racist”. Clinton said “any woman who thinks this couldn’t be directed at her is living in a dream world.”

On Tuesday’s broadcast of FOX & Friends, network host Bill O’Reilly joked he couldn’t take Democratic Rep. Maxine Waters seriously because he was looking at her “James Brown wig.”

“Just look at all that’s happened in the last few days to women who were simply doing their jobs,” Clinton said today. “April Ryan, an immensely respected journalist with unrivaled integrity, was doing her job just this afternoon, and she was patronized and cut off as she tried to ask a question.”

“One of your own California Congresswomen, Maxine Waters, was taunted with a racist joke about her hair,” Clinton said, referencing Bill O’Reilly. “Too many women, especially women of color, have had a lifetime of practice taking precisely these kinds of indignities in stride. Any woman who thinks this couldn’t be directed at her is living in a dream world.”

“There’s no place I’d rather be with you, other than the White House,” Clinton told the crowd.

Clinton spoke about sexual harassment in one of her first public speeches since losing the 2016 U.S. presidential election.
