John Shirts has taken over as U.S. attorney for Idaho, returning a former federal prosecutor and state legislator to an office responsible for federal law enforcement across all 44 Idaho counties. Attorney General Todd Blanche made the appointment effective October 18, according to the Justice Department’s October 19 [announcement](https://www.justice.gov/usao-id/pr/john-shirts-appointed-united-states-attorney-district-idaho?ref=theamericanquorum.com).

U.S. Chief District Judge Amanda K. Brailsford administered the oath in a private ceremony October 18\. The appointment follows Bart Davis’s retirement, effective October 17, establishing consecutive dates for the handoff. Davis had announced his departure in its October 7 [department release](https://www.justice.gov/usao-id/pr/us-attorney-bart-m-davis-announces-retirement?ref=theamericanquorum.com).

## A statewide federal responsibility

The district’s responsibilities extend beyond criminal trials. Its three staffed offices—in Boise, Coeur d’Alene and Pocatello—also defend the United States in civil litigation and collect debts owed to the federal government. The department’s [retirement notice](https://www.justice.gov/usao-id/pr/us-attorney-bart-m-davis-announces-retirement?ref=theamericanquorum.com) lists 65 employees, including 33 attorneys, providing a measure of the institution Shirts now leads.

Shirts said the office would continue pursuing terrorism, drug trafficking, violent crime, human trafficking, immigration offenses and fraud. Those statements identify his announced priorities; they do not establish a new charging policy or a change in any individual case. The [Capital Sun](https://idahocapitalsun.com/2026/10/19/idaho-legislator-selected-to-serve-as-states-next-u-s-attorney-after-davis-retires/?ref=theamericanquorum.com) independently reported the appointment October 19 and described the office’s statewide prosecutorial role.

The outgoing administration’s workload supplies additional context. In its [retirement account](https://www.justice.gov/usao-id/pr/us-attorney-bart-m-davis-announces-retirement?ref=theamericanquorum.com), the department said the office filed 298 criminal cases charging 337 defendants over the preceding year. It also reported filing or defending 355 civil cases during Davis’s tenure and collecting $9.2 million from civil and criminal judgments. These are department-reported activity totals, not an independent assessment of prosecutorial effectiveness.

## A return to prosecution

Shirts worked as an assistant U.S. attorney in Idaho from 2018 through 2024, prosecuting cases in Pocatello and Boise, according to his [official biography](https://www.justice.gov/usao-id/pr/john-shirts-appointed-united-states-attorney-district-idaho?ref=theamericanquorum.com). His earlier experience included an Idaho judicial clerkship and service as an Air Force judge advocate, followed by continued prosecutorial work in the Air Force Reserve. He attended the University of Idaho before graduating from the University of Colorado Law School. That background means the appointment brings back someone familiar with the district’s operations.

His transition from the Legislature requires a separate distinction. The Justice Department describes his most recent state role as representing District 9, including service as vice chair of the Agricultural Affairs Committee. But its announcement does not state whether he formally resigned his House seat. The [Capital Sun](https://idahocapitalsun.com/2026/10/19/idaho-legislator-selected-to-serve-as-states-next-u-s-attorney-after-davis-retires/?ref=theamericanquorum.com) also identified that omission. The federal appointment should therefore not be treated as documentation of a completed state legislative succession.

Davis, too, had a legislative career before federal service: the department’s [published record](https://www.justice.gov/usao-id/pr/us-attorney-bart-m-davis-announces-retirement?ref=theamericanquorum.com) credits him with 19 years in the Idaho Senate, including 15 as majority leader. For Idaho, the immediate confirmed change is leadership of the federal prosecutor’s office—not an announced restructuring of its statewide responsibilities.
