About 40 leaders of immigration reform advocacy organizations were arrested Thursday on Capitol Hill. The group was there as part of a protest aimed at pressuring the House GOP into passing an immigration reform bill with a pathway to citizenship. Taking a page from young undocumented immigrants, or Dreamers, nine of whom were arrested along the Arizona border last week, the veteran activists blocked traffic along a street adjacent to the Capitol while chanting a slogan popular among Dreamers: “Undocumented, unafraid!”
