When the Fast for Families bus rolled into Springfield, Delaware County on Wednesday, Sister Mary Beth Hamm of the Sisters of Saint Joseph was there.

The bus and its changing cast of passenger-protesters left Los Angeles on Feb. 24 and has stopped in key Congressional districts nationwide to press for immigration reform...

Last November, Fast for Families drew national attention when some of its leaders and supporters fasted for 22 days in a tent near the U.S. Capitol. Lisa Sharon Harper, of Sojourners, a Washington social justice group, was one of them and was on the bus Wednesday. She grew up in Philadelphia.
