PIERRE, S.D. (AP) — South Dakota Gov. Kristi Noem is endorsing former attorney general Marty Jackley, her one-time political rival, as he campaigns to unseat the current Republican attorney general. Jackley returned the favor for Noem’s reelection bid. The mutual endorsements represented a potential political alliance between the two Republicans. In 2018, they competed for their party’s nomination in a bitter primary. Jackley eventually endorsed Noem late in the 2018 general election campaign. Jackley is running for his old job as attorney general as current Attorney General Jason Ravnsborg faces a House impeachment investigation for his conduct surrounding a 2020 fatal car crash.
