SAN DIEGO, CALIFORNIA - MAY 13: A U.S. Border Patrol agent keeps watch as immigrants enter a vehicle to be transported from a makeshift camp between border walls, between the U.S. and Mexico, on May 13, 2023 in San Diego, California. Some of the immigrants at the open air camp have been waiting for days in limbo for a chance to plead for asylum while local volunteer groups are providing food and other necessities. The U.S. government's Covid-era Title 42 policy, which for the past three years had allowed for the quick expulsion of irregular migrants entering the country, expired on the evening of May 11.
