WASHINGTON — Roughly half a dozen federal prosecutors in Minnesota have resigned and several supervisors in the criminal section of the Justice Department’s Civil Rights Division have given notice of their departures amid turmoil over the federal investigation into the killing of a woman by a U.S. Immigration and Customs Enforcement officer in Minneapolis, according to people familiar with the matter.

The resignations follow growing tensions over a decision by the Trump administration to block the state out of the investigation into the shooting of Renee Good, who was fatally shot in the head by an immigration agent last week. Lawyers in the Civil Rights Division, which generally investigates high-profile officer shootings, were also recently told that the division would not be involved at this stage in the probe, two people familiar with the matter said.

Among the departures in Minnesota is First Assistant U.S. Attorney Joe Thompson, who had been leading the sprawling investigation and prosecution of fraud schemes in the state, two other people said. At least four other prosecutors in the Minnesota U.S. attorney’s office joined Thompson in resigning amid a period of tension in the office, the people said. The people spoke on the condition of anonymity to discuss personnel matters.

They are the latest in an exodus of career Justice Department attorneys who have resigned or been forced out over concerns over political pressure or shifting priorities under the Trump administration. Hundreds of Justice Department lawyers have been fired or have left voluntarily over the last year.

Minnesota Democratic lawmakers criticized the departures, with Sen. Amy Klobuchar, a member of the Senate Judiciary Committee, calling the resignations “a loss for our state and for public safety” and warning that prosecutions should not be driven by politics.
