More than a dozen California members of Congress are demanding answers from the Department of Homeland Security after about 100 federal agents decked out in tactical gear and masks showed up outside an event over redistricting. 

The lawmakers are seeking the true motives behind the large show of force outside the Aug. 14 event in Los Angeles, where California Gov. Gavin Newsom (D), Democratic lawmakers, members of the independent redistricting commission, and others spoke about the newly drawn congressional district maps.
