AUSTIN, Texas (AP) — Texas must move a large floating barrier that Gov. Greg Abbott placed on the river between the U.S. and Mexico this summer as part of the Republican’s escalating attempts to stop migrants from crossing America’s southern border, a federal judge ruled Wednesday.

Texas state police officers separated migrant families along the border with Mexico by detaining fathers on trespassing charges and turning over mothers and children to federal officials, the state Department of Public Safety said Thursday.

Thursday is the start of Hispanic Heritage Month, four weeks of celebrating Latino contributions not just to the United States, but to the entire hemisphere. Meanwhile, Republicans have decided to treat Latinos seeking sanctuary like vermin.

The new findings that a culture of lockdowns in Uvalde played some role in the failures on May 24 reflects how one of the worst school shootings in U.S. history intersected with immigration policies and thousands of Border Patrol agents, National Guard members, and state police assigned to apprehend migrants and stop drug traffickers.

The U.S. Department of Justice is investigating potential civil rights violations in Texas’ multibillion-dollar border security mission that has given the National Guard arrest powers and seen state authorities bus migrants to Washington, D.C., according to public records.

The governor’s decision to go all in on border security is evolving rapidly, and many of those on the ground don’t know how it’s going to work.
