Some 750,000 people flooded the streets of downtown Los Angeles Saturday to march in solidarity with the Women's March on Washington, according to organizers for the event.
Event organizers for the Women's March-Los Angeles say the day is designed to unify communities and make a stand for "justice and equity for all."
The mission statement for the march reads in part, "We stand together in solidarity for the protection of our rights, our safety, our health and our families -- recognizing that our vibrant and diverse communities are the strength of our country."
The march came a day after Donald Trump's inauguration. Although it appears nowhere on the site for the event, the march appears to be in direct response to the election of Trump. But organizers have to be clear to point out the march will be "pro-woman" rather than "anti-Trump.
Thousands Attend Women's March in Downtown Los Angeles
"Women's March Los Angeles is about having our voices heard, activating our community and unifying our community. Women's rights are human rights," said organizer Emiliana Guereca.
Organizers for Women's March Los Angeles estimated three-quarters of a million people came out for the event. The Los Angeles Police Department deferred to the organizers for the march when asked about a crowd estimate.
The march in LA is a sister march to a massive gathering planned in Washington, D.C., where hundreds of thousands of people are expected to turn out, including Gloria Steinem as well as many celebrities like America Ferrera, Ashley Judd, and others.
Marchers in Los Angeles enjoyed a break in the rain between a series of storms that have drenched Southern California this week.
Participants began meeting at Pershing Square at 9 a.m., and the official march was slated to commence at 10 a.m. The march was expected to end at City Hall, and speakers including Los Angeles County Supervisor Hilda Solis, Mayor Eric Garcetti, and former Mayor Antonio Villaraigosa are expected to attend. Other notable attendees include Jane Fonda, Laverne Cox, Debbie Allen, Miley Cyrus and Ariana Grande.
Los Angeles County Supervisor Janice Hahn was also planning to attend.

"I am marching Saturday because I want to show my support for the millions of Americans who continue to believe that we should be a nation that respects and supports everyone whether they are a woman, a man, an immigrant, gay, straight, trans, poor or Muslim," Hahn said. "We need to lead by example and fight to make Los Angeles County a model for the nation."
As of Saturday morning, 93,000 people said they were attending on the event's Facebook page, and another 73,000 noted they were interested in attending the event.
Street closures will be in place and traffic delays are expected due to the march, which is expected to end at 4 p.m.
Trains on the Metrolink's San Bernardino and Antelope Valley lines were at capacity Saturday morning and could not pick up additional passengers as they traveled to Union Station, said Scott Johnson a spokesman for Metrolink. The San Bernardino Line was carrying about 1,000 people, and the Antelope Valley line out of Lancaster was carrying about 600.
Amtrack 763, traveling through Orange County, was also at capacity but Johnson could not confirm whether or not it was picking up additional passengers.
