The Women’s March on Washington, a mobile protest organized in response to President Trump’s election, is under way in downtown Washington, D.C.

The event’s organizers are anticipating roughly 250,000 marchers, many of whom supported Hillary Clinton for president and are wary about the new administration’s policies towards women, as well as its approach toward the LGBT community, minorities, immigrant groups, and others. According to the march’s mission statement, participants aim to “send a bold message to our new government on their first day in office, and to the world, that women’s rights are human rights.” Six hundred similar marches are being held Saturday around the country. Others have been organized around the world.

In Washington, a morning rally will be held at 10 a.m. ET, and the march will begin at 1:15 p.m. ET. We’ll bring you the latest updates from the nation’s capital as the day goes on.
