The National Park Service is now prepared for 10 times that - 50,000 people - to rally outside the White House and march on the Department of Justice, according to a permit issued this week.

The women chanted slogans such as "we care" and "where are the children" in a largely peaceful standoff with police, who ordered them to leave. "This is not a bad enough crime to lock them up and take their children away". The groups hope the events draw hundreds of thousands of people.
