Mitt Romney takes a new position at son's firm

BOSTON (AP) - Mitt Romney has a new position with his son's Boston-area venture capital firm.

Last year's Republican presidential nominee will serve as chairman of the executive committee for Solamere Capital . The firm was founded by Romney's oldest son, Tagg, and the national finance committee chairman for his presidential campaign, Spencer Zwick.

Romney has been a limited partner in Solamere, and investors have been sent letters announcing his elevated role. The Associated Press obtained a copy of one of the letters on Wednesday.

Romney has just begun to emerge from months of isolation at his home in southern California. In a Sunday television interview, he said "it kills me" to have lost the presidential race.

He delivers his first public speech since the loss next week in Washington.
