On June 28, 2018 more than one thousand women from all over the US marched from the Freedom Plaza in Washington, DC, to Capitol Hill for a peaceful protest and sit-in at The Hart Senate Office Building over the Trump administration's "zero tolerance" immigration policy which called for separating children from their parents. At least 575 women were arrested.

The march and civil disobedience in the Capitol was organized by the Women's March, the Center for Popular Democracy, and CASA in Action
