Congressional representatives and human rights organizations have raised concerns about conditions at immigration detention facilities in Texas, highlighting issues at two separate locations along the border.

Representative Maxine Dexter, a Democratic congresswoman from Oregon, sent a letter to refugee and health officials on May 8 questioning the treatment of pregnant, unaccompanied minors at the San Benito facility near the Texas-Mexico border. Dexter, a former critical care physician, visited the facility but reported being prevented from speaking with any of the children housed there.

In her letter, Dexter asked why pregnant minors were concentrated at the San Benito location and whether they receive adequate medical care given their high-risk conditions and Texas's abortion restrictions. She also inquired about the current whereabouts of the girls and any infants born while in custody.

Separately, human rights groups including the American Civil Liberties Union filed a lawsuit on Friday against Immigration and Customs Enforcement regarding conditions at Camp East Montana in El Paso, Texas. The facility is described as the largest immigration detention center in the United States.

The lawsuit, filed by the ACLU, Human Rights Watch, and the Texas Civil Rights Project, alleges abuse and inhumane conditions at the El Paso facility. The groups are seeking to address what they characterize as systemic problems within the immigration detention system.

As of the reporting date, Dexter had not received responses to her inquiries about the San Benito facility, according to her office.
