LINCOLN, Neb. (AP) — Nebraska Attorney General Doug Peterson won’t seek a third term in office in 2022.

The Lincoln Journal Star reports that Peterson announced his plans in a note to family and friends that the newspaper obtained Saturday.

Peterson is a Republican who served as assistant state attorney general before he was first elected in 2014. He ran unopposed in 2018.

Peterson said in his note that “it has been a unique privilege to serve our state as Attorney General.” During his time in office, Peterson challenged several policies established by the Barack Obama and Joe Biden administrations.
