Three Democratic congressmen are demanding that the Department of Homeland Security and the Department of Justice produce documents related to immigration raids at seven Mississippi chicken processing plants.

They want Attorney General Bill Barr and Acting Homeland Security Secretary Kevin McAleenan to detail the cost of raids that initially detained 680 people and whether employers face criminal charges. They also want to know whether any U.S. citizens were detained, how many parents were separated from children, whether any still remain separated.

House Homeland Security Committee Chairman Bennie Thompson of Mississippi made the demand Friday, along with House Oversight and Reform Committee Chairman Elijah Cummings of Maryland and House Subcommittee on Civil Rights and Civil Liberties Chairman Jamie Raskin of Maryland.

The three question the raid at Koch Foods in Morton.
