SALT LAKE CITY (AP) — Former GOP presidential nominee Mitt Romney is running for the Senate in Utah. Three people with direct knowledge of the plan say Romney will formally launch his campaign in a video on Thursday. His first public appearance as a Senate candidate will come Friday in Utah. The 70-year-old Republican is seeking to replace Republican Sen. Orrin Hatch, who is retiring after more than 40 years in the U.S. Senate.
