FILE - In this March 5, 2018, file photo, boys look through an older section of the border structure from Mexicali, Mexico, alongside a newly-constructed, taller section, left, in Calexico, Calif. A federal appeals court has rejected arguments by the state of California and environmental groups who tried to block reconstruction of sections of the U.S.-Mexico border wall. The 9th U.S. Circuit Court of Appeals ruled Monday, Feb. 11, 2019, that the Trump administration did not exceed its authority by waiving environmental regulations to rebuild sections of wall near San Diego and Calexico.
