Seventy House Democrats are backing an effort to impeach Homeland Security Secretary Kristi Noem, in the wake of the fatal shooting of a 37-year-old woman in Minneapolis by a federal immigration agent.

Democratic Rep. Robin Kelly of Illinois formally introduced three articles of impeachment against Noem on Wednesday, including obstruction of Congress, violation of public trust, and self-dealing. Seventy members of Congress—all Democrats—are co-sponsoring the articles of impeachment, according to a press release from Kelly’s office.
