Texas Governor Greg Abbott has signed into law SB4, a sweeping new immigration bill that gives state law enforcement the power to arrest and seek the deportation of migrants suspected of crossing the border illegally. The bill has been met with strong opposition from civil rights groups, and is likely to face legal challenges in the coming months. Attorney General Ken Paxton has defended the bill, saying it is necessary to protect Texans from “dangerous criminals” and does not authorize racial profiling.
