Per a campaign source, NBC News has learned that former Massachusetts Gov. Mitt Romney (R) will officially announce he's running for president on Tuesday, Feb. 13, in his native Michigan. After this announcement in Dearborn, first reported by The Politico, Romney will then travel to Iowa, New Hampshire, and South Carolina over the next two days. And then on Feb. 15, he'll return to Boston, where he'll hold another major fundraiser at the Boston Convention and Exhibition Center.
Michigan, of course, is not only the site of a key early GOP nominating contest, but it's also the state where Romney's father served as governor.
