WATCH LIVE: Women's March on Washington, anti-Trump protesters

Hundreds of thousands of people are expected to file into downtown Washington on Saturday for the Women's March on Washington, D.C., in hopes of sending sending "a bold message" to the new administration under President Donald Trump.

The event will feature speakers, celebrity appearances and a protest walk along the National Mall planned as a counter-argument to Trump's presidential campaign. The protest is also a global event, with thousands more joining marches all across the world.
