The Women's March on Washington

Organizers say more than 500,000 people came to the Women's March on Washington, DC to protest the policies of the newly inaugurated President Donald Trump.

Crowds along Independence Avenue where the rally was held were shoulder to shoulder. Mobile internet service was jammed from 10 a.m. until about 3:30 p.m. when the crowd began moving.

The DC Metro reported 275,000 rides as of 11 a.m. on Saturday. This was 82,000 more than the 193,000 reported at the same time on Friday, which was Donald Trump's inauguration day. Rider volume was eight times greater than is typical on a Saturday, officials said.

Girls stood along the Smithsonian's Air and Space Museum on 4th Street knitting pink beanies with cat ears, called "pussy hats," as a symbol of solidarity among protestors. A group called the Pussyhat Project made the pattern available for free on its website ahead of the march and encouraged women to download it and knit or crochet hats for the march.

This banner that read "Hear me roar in numbers too big to ignore" was hung near the steps of the Smithsonian's National Gallery under a temporary cellular tower. Wireless operators said they spent two years updating their networks to prepare for the inauguration and had deployed temporary infrastructure to deal with large crowds.

Hundreds of thousands of women showed up to the march, many of them with their husbands, boyfriends, and sons. These men stood along the National Mall holding their signs high.

The large concentration of people in a small area who were all trying to tweet, Snapchat, post photos to Instagram, stream live video on Facebook, and text message each other overwhelmed major mobile networks for much of the day.

Cecile Richards, president of Planned Parenthood said, "Our doors will stay open!" Access to health care and abortions was a big theme throughout the Women's March rally.

Filmmaker Michael Moore asked women at the March to call their elected officials every day. He said he'd put out a call to action on his Facebook page daily. He said if women flood the congressional switchboard, they will force change.

Feminist icon Gloria Steinem tells women at the March "No more asking daddy. We are linked; we are not ranked and this is the day that will change us forever because we are together."

The Women's March had to be rerouted because the crowds were too large, preventing organizers from leading a formal march toward the White House.

Organizers had expected 200,000 in Washington, DC for the Women's March. No official count has been released, but organizers say more than 500,000 attended.

Actress Scarlett Johansson talked to the crowd about her support for Planned Parenthood.

Cell phone networks were overloaded Saturday and most people experienced delays sharing photos and video of the March. The closer one got to the National Mall and as crowds dispersed, service improved. Most of the temporary infrastructure had been placed along the Mall for the inauguration.

The organizers of the Women's March worked with the disability community to ensure the march was accessible for people of all abilities. The Women's March Disability Caucus, a group formed on Facebook, worked with national organizing committee to set up an Americans with Disabilities Act, or ADA, tent at the rally, which offered volunteers to assist people who needed it for the march.

Ahead of Friday's inauguration, planners covered up signs on porta-potties along the National Mall with the president's first name "Don John." On Saturday, protestors tore off the pieces of paper covering it.
