SPRINGFIELD (Delaware County), Pa. (CBS) — “Fast for Families” is a movement for immigration reform that started at the Capitol in DC last fall.

Now they are taking the show on the road, in a decorated bus, making stops in the Greater Philadelphia area...

“We’ve been calling on people to fast because now is the time,” said Lisa Sharon Harper (at lectern in photo), who works for the DC-based Sojourners.

Harper says she and many others fasted for 22 days last November just feet from the US Capitol. And she says their effort caused lawmakers to come to their tent and listen to the stories of immigrants.
