21 January 2017
Protesters in Washington, D.C., and worldwide gathered Saturday for the Women’s March on Washington and other demonstrations following the inauguration of President Donald Trump. Thousands of people flooded Metro trains and other forms of public transportation and traveled from across the nation to gather outside the White House for the march on Saturday morning. By Saturday afternoon, people packed into common areas wearing pink hats in solidarity. …
Heavy traffic was also reported coming from Northern Virginia and Maryland into Washington D.C. and multiple parking garages began to fill up as people arrived from surrounding states for the march, according to the Washington Post. The march, which began as a movement on Facebook, quickly spawned more than 600 “sister marches” in major U.S. cities outside of Washington D.C. and international marches in Sydney, Hong Kong, London, Rome and Paris [and many other places], according to CNN. Some 2.2 million people were expected to participate worldwide.
