Salt Lake County councilwoman Jenny Wilson is running to challenge Orrin Hatch for his Senate seat next year.
The Democrat serving her second six-year term on the council said Monday that it's time for a change after Hatch's 40 years in office.
Wilson, the daughter of former Salt Lake City mayor Ted Wilson, has served on a number of nonprofit boards and produced and directed a documentary film about a rescue on Grand Teton.
Hatch says he intends to run for re-election in 2018 but the Republican senator has not made a final decision on whether he'll actually seek another term.
Hatch's spokesman Matt Whitlock said in a statement that the senator's role as chair of the Senate Finance committee puts him at the center of critical debates and he'll win if he runs for re-election.
