Beatings. Sexual assault. Psychological abuse. These are some of the horrors endured by the more than 250 men the United States sent to El Salvador on flimsy evidence of gang membership, according to a new comprehensive report released on Wednesday by Human Rights Watch and Cristosal, a human rights group focused on Central America.

In early 2025, the Trump administration flew Venezuelan migrants to Salvadoran President Nayib Bukele’s notorious Terrorism Confinement Center, where they were held for four months without communication with their families and lawyers. The US government had accused the men of being members of the transnational gang Tren de Aragua and removed most of them from the United States under the Alien Enemies Act—an 18th-century law that President Donald Trump has invoked for only the fourth time in US history.

As Mother Jones and other outlets have reported extensively, most of the men had no serious criminal history in the United States or elsewhere in the world. What they often had instead were tattoos that bore no relation to the gang.

The new report offers even more evidence of the inhumane treatment the Venezuelan migrants endured in El Salvador. Based on the testimonies of 40 men who were detained at CECOT, as well as interviews with 150 other people—including lawyers and relatives in Venezuela, Colombia, and the United States—it paints a damning picture of the abuses inflicted at CECOT.
