How protest signs are being used at the Women's March
While the reasons why people are participating vary, President Donald Trump has been a core source of frustration for many, including Rachael Ryan in New York City. Ryan joined roughly 3,000 other people Saturday near Central Park to stand against the President.
"These protests are hugely important. We cannot have four more years of Trump. He has done too much damage already," Ryan told CNN on Twitter.
Ryan spotted a group of protesters in New York holding signs that read: "My milkshake brings all the girls to the MARCH," "Feminism: the radical notion that women are people" and "Girls just wanna have fundamental rights."
Another common theme seen on protest signs around the US was reproductive rights. Linda Webb saw many signs in that vein in St. Louis.
"We will stand up [for] women's rights and equality! HUGE crowd. So many young women here who are fighting for their future," Webb tweeted.
Webb snapped two photos of women in St. Louis holding signs that read, "My body my choice," "Who run the world" GIRLS" and "No sign is big enough to list all the reasons I'm here."
The Women's March began in response to Trump's election and has since transformed into a nationwide movement. According to the Women's March website, organizers follow eight "unity principles:" ending violence; protecting reproductive rights, LGBTQIA rights, worker's rights, civil rights, disability rights and immigrant rights; and environmental justice.
The march is intended to " harness the political power of diverse women and their communities to create transformative social change."
