Trump addressed the rallies on his Twitter account on Saturday. "Lowest female unemployment in 18 years!"
"So while we have this president celebrating his one-year anniversary, let's give him an "F" (grade) for his performance", House of Representatives Minority Leader Nancy Pelosi said while flanked by fellow Democrats.
On both days, many not only supported women's rights, but also denounced President Donald Trump's views on immigration, abortion, LGBT rights and women's rights on Saturday - the anniversary of his inauguration - and Sunday, the first anniversary of the massive wave of protest marches.
Organisers have hailed it as a new era of political activism, saying they are hoping to keep up the momentum from last year's anti-Trump march, which became one of the biggest mass protests in USA history. "It's an important year because we can vote to reclaim the House and Senate and deny power to the president", she told Efe, referring to the midterm elections to be held in November.
Numerous women marching over the weekend were rallying for a number of issues, not all related to women's rights.
"I'm out here because I'm a victim of sexual assault and I really fell like I need to join in, speaking out about just the disgusting people that get away with stuff like this", said Rachel Beondesen.
"That is why we are urging people to register to vote today".
Crowd estimates for the Washington march were down from a year ago. "Use your power for progress and we are more powerful together".

In the intervening year, a string of reports laying bare pervasive sexual harassment and misconduct in workplaces from Washington D.C.'s Capitol Hill to Hollywood's studios have added further texture to the movement, with anti-Trump fervor remaining at, or at least near, its core.
Among public figures addressing the protesters in the U.S. capital were senior Democratic Party leaders, who remained in Washington for the weekend due to the government shutdown. "It's time for you to run", said Jordan, who would be the first Native American governor in the US and the first woman governor of Idaho, The Arizona Republic reports.
Bingham and other activists point to a shift in the way women's voices have been heard and acknowledged in the months since the original march. "I've lived through decades of sexual harassment issues and it's getting better-but it's nowhere near where it needs to be", the 51-year-old said, sporting a Wonder Woman costume in coordination with her daughter. "And when I ask for it. like if you ask for it, 'You're a b--.' If you don't ask for it, they just run you over".
