Former Secretary of State Colin Powell says illegal immigrants do essential work in the U.S. and he has firsthand knowledge of that — because they fix his house. Powell, a moderate Republican, urged his party Sunday to support immigration generally because it is "what's keeping this country's lifeblood moving forward." In an interview with NBC's "Meet the Press," he said a path to legal status should be offered to illegal immigrants because they "are doing things we need done in this country."
