MANCHESTER, N.H. – Trading accusations of greed, Mitt Romney and Newt Gingrich challenged each other Monday to return millions made in private business as the race for the GOP presidential nomination turned increasingly acerbic and personal at the start of a three-week sprint to the Iowa caucuses.
Far from Iowa, the two men campaigned miles apart from each other in next-up New Hampshire, where Romney has long dominated in polls but where Gingrich is aggressively working to make inroads.
Romney called on Gingrich to return the estimated $1.6 million he received for providing strategic advice to Freddie Mac, the quasi-government agency that guarantees home mortgages. Gingrich has said he acted as a historian, not a lobbyist.
