House Democrats from Texas went after Gov. Greg Abbott ® on Sunday over a standoff at the U.S.-Mexico border between state and federal law enforcement, accusing him of inciting potential violence and making border safety a purely political issue.

Rep. Joaquin Castro (D-Texas) described Abbott’s border security program as a “disaster” and part of the “most virulent anti-immigrant sentiment in a generation.”

The governor appeared to ignore a Supreme Court order last month that allowed federal Border Patrol to remove barriers erected by state law enforcement. Abbott shrugged off the order, claiming that state law “supersedes” federal.

Dozens of GOP governors have backed Abbott in the fight, with some pledging material assistance, including National Guard troops.
