Chicago Pastor Courtney Lewis said he was in the middle of delivering a sermon to his congregation Sunday when he heard loud banging on the church doors. It was the police sent by the city's Democratic Mayor Lori Lightfoot. Lightfoot had allegedly dispatched officers in three squad cars along with two unmarked vehicles in order to shut down the service at Cornerstone Baptist Church, Lewis claimed in a letter of grievance to U.S. Attorney John Lausch.
