The government has deported hundreds of migrants over alleged gang ties, but their families claim their loved ones are innocent and lack due process.

The Trump administration says it has deported 17 more “violent criminals” from the Tren de Aragua and MS-13 gangs to El Salvador, as it doubles down on a policy of removing people from the U.S. to third countries despite criticism over lack of transparency and human rights protections.

Earlier this month, President Donald Trump used the Alien Enemies Act to deport 238 Venezuelans from the United States—sending them not to their home country, but to a prison in El Salvador notorious for its harsh conditions.
