328 Chinese Nationals have been caught trying to enter the United States illegally this year, and left-wing groups like the American Civil Liberties Union (ACLU) are fighting to have them released into the country.

Acting Homeland Security Secretary Chad Wolf noted that legal challenges to the Trump administration’s Migrant Protection Protocols (MPP) policy could result in potentially dangerous migrants, such as these 328 Chinese Nationals, being released into the U.S. Many of these migrants are being kept on the Mexican side of the border because of the MPP.

“MPP has an uncertain future. We know from experience that the journey to the U.S. border puts migrants in poor conditions — and they often arrive with no passports, medical histories, or travel manifests. The administration will continue to closely monitor the virus globally, as well as in our hemisphere, and will adjust our proactive measures as necessary,” Wolf said.
