Katherine Figueroa was 9 and watching television reports of a workplace raid in Phoenix when she saw video of her parents being hauled away by sheriff’s deputies. They were eventually released, but the episode was jarring enough that Katherine, now 13, and her parents traveled to Washington to lobby lawmakers and rally with others Wednesday outside the White House against further deportations. About 100 immigrants who are in the country illegally converged on the White House as part of a project called #Not1More, to sing, march and chant for their cause. “Their dream is to be here,” Katherine said of her parents, at a Capitol Hill briefing with congressional staff. Nearly a dozen Arizonans took part in the rally to call for comprehensive immigration reform and an end to “Se Communities,” an Immigration and Customs Enforcement program that checks immigration status and criminal histories of people who are arrested.
