Border troops arrive: Texas became the first state to deploy National Guard troops to the U.S.Mexico border last week, as part of a security buildup ordered by President Trump, who has been increasingly frustrated by his inability to build a border wall. The Republican governors of Texas, Arizona, and New Mexico have pledged a total of 1,600 National Guard troops, with nearly 700 personnel already dispatched. California, whose Democratic Gov. Jerry Brown has clashed bitterly with Trump over immigration policy, will mobilize 400 troops. Defense Secretary James Mattis has approved Pentagon funding for up to 4,000 National Guard border personnel through the end of September. The Guard units will serve in support roles, assisting civilian law enforcement with activities like surveillance, but they will not make arrests or carry guns. “That is not their role,” said Texas Gov. Greg Abbott.
