(NBC)- Political tensions in Minneapolis escalated overnight after Minnesota Congresswoman Ilhan Omar was confronted at a town hall meeting by a man who attempted to spray her with an unknown substance before being dragged out and arrested. Shortly before the town hall, Omar publicly called for the resignation of Homeland Security Secretary Kristi Noem. Republican Senator Lisa Murkowski of Alaska said she has lost confidence in Secretary Noem, citing disappointment in her leadership. At least 162 House Democrats are now backing an effort to impeach Homeland Security Secretary Noem.
