U.S. Customs and Border Protection officers stand in the vehicle lanes during a show of force and exercise to secure the San Ysidro Port of Entry Nov. 22 in San Diego. Several hundred officers as well as military personnel were seen participating in the exercise, which had the border crossing closed for about 30 minutes. The show of force and exercise was in response to the presence of a large caravan of mainly Honduran migrants that recently arrived in neighboring Tijuana, Mexico. (CNS photo/David Maung)
