A swarm of black and white patrol units passed through San Diego Tuesday afternoon as they headed towards the Eagle Pass border.

"DPS continues to provide direct support to local, state and federal partners, including United States Border Patrol, to enhance security along the border and to combat drug and human smuggling into Texas and the nation," said Sgt. Nathan Brandley with the Department of Public Safety.

According to the Eagle Pass News Leader, 500 state troopers are headed towards the border to assist with immigration.
