Arizona human rights activist charged with harboring two migrants who crossed the U.S.-Mexico border illegally testified that he told the men he "could not hide them" but let them stay in a building while they recovered from a desert trek.
Scott Warren, 37, appeared on Tuesday in his second federal felony trial this year after a Tucson jury was unable to reach a verdict in June on whether he broke the law by giving food, water and shelter to two Central
American migrants.

Donald Trump makes tougher
immigration enforcement a major re-election theme.
