Gov. Greg Abbott on Wednesday called for the federal government to close a San Antonio facility housing unaccompanied migrant children after he became aware of allegations of sexual assault.

“In short, this facility is a health and safety nightmare,” Abbott said at a press conference outside the Freeman Coliseum, which is reportedly housing more than 1,300 teens who recently crossed the U.S.-Mexico border without a parent or guardian.

The announcement came as Texas and the federal government are locked in battle over a recent increase in the number of migrants crossing the state’s southern border. From The Texas Tribune.
