On the Saturday, January 21, 2017 following President Donald Trump's inauguration, hundreds of thousands of protesters gathered in Washington, D.C. for the Women's March on Washington. Marchers from all over the country converged to protest issues from affordable healthcare, to immigration law, to access to abortion services. Similar marches took place around the world. So many people gathered on the National Mall that demonstrators ultimately marched up several streets, instead of the single route to the White House initially intended.
