The New York Times is reporting Immigration and Customs Enforcement raids will begin Sunday.
ICE officials will reportedly arrested thousands of undocumented immigrants including those who may not be targeted but happen to be on the scene.
The agency originally planned to arrest families with court ordered removals in ten cities last month.
President Trump delayed that operation to give Democrats and Republicans time to reach an agreement on the migrant crisis.
That has not happened yet.
Acting US Citizen and Immigration Services Director Ken Cuccinelli said Wednesday the raids are “absolutely going to happen,” though he declined to say when.
According to the Times, officials say authorities will try not to split up detained families.
