WASHINGTON (Reuters) - Former Republican presidential candidate Mitt Romney will run for a U.S. Senate seat representing Utah and plans to announce his bid online on Thursday, a source familiar with Romney's plans said.


Romney will pledge to "bring Utah values to Washington, D.C." and plan to run a very Utah-centric campaign, the source said on Wednesday.
