PORTLAND, Maine (AP) — U.S. Sen. Susan Collins of Maine said Thursday that immigration officials have ceased their “enhanced operations” in the state, the site of an enforcement surge and more than 100 arrests since last week. Collins, a Republican, made the announcement after saying she had several direct communications with Secretary of Homeland Security Kristi Noem. “There are currently no ongoing or planned large-scale ICE operations here,” Collins said in a statement. Mills has challenged immigration officials to provide judicial warrants, real-time arrest numbers and basic information about who is being detained in Maine . Mills’ office did not immediately respond to an Associated Press email seeking comment from the governor on Collins’ announcement.
