U.S. Homeland Security Secretary Kristi Noem on Wednesday visited the high-security El Salvador prison where Venezuelans who the Trump administration alleges are gang members have been held since their removal from the United States. The tour included two crowded cell blocks, the armory and an isolation unit.

Noem's trip to the prison — where inmates are packed into cells and never allowed outside — comes as the Trump administration seeks to show it is deporting people it describes as the "worst of the worst."

The Trump administration is arguing in federal court that it was justified in sending the Venezuelans to El Salvador, while activists say officials have sent them to a prison rife with human rights abuses while presenting little evidence that they were part of the Venezuelan Tren de Aragua gang.
