SAN YSIDRO, Calif. (KGTV) – A Customs and Border Protection training exercise caused some travel delays at the San Ysidro Port of Entry Thursday afternoon.
The "large-scale operational readiness excercise" took place at 1 p.m. and lasted approximately 10 minutes. Officials informed anyone traveling to and from the port of entry to “be aware of high visibility operations.”
During the drill, CBP officers could be seen setting off smoke devices and holding up clear plastic shields on the U.S. side of the port. Officers then formed a line and and walked into a building in the area.
Protesters with "Veterans for Peace" watched the drill carrying signs that read "Resist Trump Tyranny". David Patterson said he was there to make sure the active duty military isn't overstepping their boundaries.
“They may be national guard but if active duty they shouldn’t be armed because that's a violation of the law," David Patterson said.
Despite the exercise, travelers weren't expected to face long processing delays.
According to CBP officials, the drill was part of their continuing enforcement efforts at the U.S.-Mexico border.
