Two South Texas lawmakers on Tuesday toured a federal detention facility in this border town where pregnant migrant teens are being sent, some as young as 13.

U.S. Reps. Vicente Gonzalez and Joaquin Castro, both Democrats, spent about an hour inside the facility, which is located downtown and across from San Benito’s museum.

After the tour, Gonzalez said they wanted to make sure the pregnant teens are getting the medical care they need and that there are facilities on site to help them.

“That they have the minimum medical standards of an American facility to care for pregnant women and we want to look after American citizens that are here now, and people with legal status that are here or in other facilities being detained,” said Gonzalez, who represents this congressional district. “We’re especially concerned with American citizens and assuring that they have the care that they deserve under the Constitution.”
