The U.S. Department of Justice said Sunday it is investigating a group of protesters in Minnesota who disrupted services at a church where a local official with U.S. Immigration and Customs Enforcement apparently serves as a pastor.

A livestreamed video posted on the Facebook page of Black Lives Matter Minnesota, one of the protest’s organizers, shows a group of people interrupting services at the Cities Church in St. Paul by chanting “ICE out” and “Justice for Renee Good.” The 37-year-old mother of three was fatally shot by an ICE agent in Minneapolis earlier this month amid a surge in federal immigration enforcement activities.

The protesters allege that one of the church’s pastors — David Easterwood — also leads the local ICE field office overseeing the operations that have involved violent tactics and illegal arrests.
