On July 13, 2018 U.S. Customs and Border Protection (CBP) released nine photos from June 19, 2018 that purport to show "new border wall construction." The US-Mexico border wall construction is reportedly happening near the "Chula Vista Area of Responsibility," despite the fact that Chula Vista, California's city limits do not touch the US-Mexico border.
These photos are in the public domain and can be used without restriction. Photos should be credited to CBP and Tim Tucciarone.
Notably, Mexico hasn't paid a dime for "the wall."
