ICE is releasing hundreds of migrants into the United States as they struggle to deal with the problem at the border. ICE is placing the blame squarely on Congress and the decades of inaction in dealing with the immigration crisis.

According to Fox News:

More than 500 migrants were released Wednesday onto the streets of Texas and New Mexico, U.S. Immigration Customs and Enforcement said, as the government struggles to detain illegal immigrants amid an influx of Central Americans trying to cross the U.S.-Mexico border.

The release on Wednesday followed days of other mass releases by the agency in order to prevent migrant families from being detained longer than allowed. On Christmas Day, the agency released 186 migrants and another 400 were set free two days prior, Las Cruces’ KVIA-TV reported.

More releases are expected Thursday, said Ruben Garcia of the Annunciation House, a homeless and refugee shelter in El Paso.

After a similar release Sunday, ICE blamed “decades of inaction by Congress” for limiting its ability to remove families who are in the U.S. illegally.

Rules state that if the migrants are not able to be placed into shelters due to overcrowding ICE has to release them into the streets of the United States.
