WASHINGTON (KDKA/AP) -- The mission statement of the Women's March on Washington says event participants are "hurting and scared" as Donald Trump takes office - and they want a greater voice for women in political life.
Look to the National Mall in Washington for lots of bright pink hats and signs that say "less fear more love" and "the future is female."
Thousands of women are set to make their voices heard on the first full day of Donald Trump's presidency.
Officials said that shortly before 1 p.m., people were standing along the entire march route and organizers couldn't lead a formal march toward the White House.
Dozens of people in the Pittsburgh area headed to Washington D.C. for the event.
A group boarded a bus bound for D.C. at Station Square in the early hours of Saturday morning.
Pamela Chambers, of Grand Rapids, Mich., carried a sign with a report card grading Donald Trump, giving him Fs in subjects including citizenship, science, history, vocabulary and reproductive health.
"We're going down to have our voices heard and protest Donald Trump's rhetoric and his policies," Chambers said.
"I'm also really happy to be meeting other people and just talking about some other things we can do in the future to work against some of his conflicts of interest," she added.
Other protests also went on in other U.S. cities, including Pittsburgh, and around the world.
Figures from transportation officials in Washington suggest more people may be on the National Mall for the women's march than came for President Donald Trump's inauguration.
Officials said organizers of the Women's March on Washington had more than doubled their turnout estimate to 500,000 as crowds began swelling and subways into the city became clogged with participants.
As of 11 a.m. Saturday, 275,000 people had taken trips on the city's subway system.
On Inauguration Day, 193,000 trips had been taken as of that time, and the rail system opened an hour earlier that day, at 4 a.m.
Saturday's ridership figures were more than eight times a normal Saturday and busier than most weekdays.
In addition, some 1,800 buses were registered to park in the city. Greyhound reported adding more buses from New York. And a commuter rail system in Washington added five times its normal capacity to help deal with the crowds.
