Many women said they came to Baltimore's rally to build on the momentum of last year's historic Women's March on Washington, when hundreds of thousands of people converged on the nation's capital to condemn Trump's fledgling presidency. Millions of people around the world marched during last year's rallies, and many on Saturday thought about all that's happened in the past year.
The president took to Twitter to ask women to celebrate the "historic milestones and unprecedented economic success" of the a year ago.
"I think right now with the #MeToo movement, it's even more important to stand for our rights", said Karen Tordivo, who marched in Cleveland with her husband and 6-year-old daughter.
The event features a slate of big names in the world of liberal activism: Cecile Richards, the president of Planned Parenthood; Melissa Harris-Perry, a professor and former MSNBC host; congressman and civil rights era icon John Lewis, D-Ga.; Alicia Garza of the Black Lives Matter movement.

Thalia Friedman, an intrepid 9-year-old NY resident, held up a sign that read: "Donald Trump calls women ugly and does not deserve to be president".
"We want to celebrate these women leaders, and encourage more women to run and join them in the General Assembly", Ramos said. "But I'm here today saying that no one and nothing can be great unless it costs you something".
Speakers at the rally before the march spoke about both national and local issues, which was different from a year ago when speakers spoke only about national issues.
But across the country, there have been protests against the Trump administration's policies.

"I'm going into this a little fearful about things I don't understand", she said.
"In 2018, it is a testament to the power and resilience of women everywhere", she tweeted, urging people to show that power at the voting booth this year.
She added: Power to the peaceful, power to the people.
