AUSTIN, Texas (AP) — Texas Attorney General Greg Abbott has asked the U.S. Homeland Security secretary for $30 million so Texas can send more state troopers to the Texas-Mexico border to provide security while the Border Patrol is contending with an immigration surge.

In a letter Thursday, Abbott, Republican nominee for Texas governor, tells Homeland Security Secretary Jeh Johnson that it would cost $1.3 million per week for the state to launch a significant border security operation.
