Central American migrants cross the shallow concrete waterway of the bordering Tijuana River on Sunday as they try to reach the El Chaparral border crossing point in Tijuana, Baja California State, Mexico. Leftists were outraged that border patrol agents used tear gas on those who tried to illegally enter the U.S. Sunday, even though rocks were thrown at agents. A similar incident took place five years ago under President Barack Obama's watch. (GUILLERMO ARIAS/AFP/Getty Images)
