Rep. Michael Grimm (R-N.Y.), a freshman from Staten Island, on Thursday became the latest Republican to call for members of the GOP presidential field to halt their attacks on former Massachusetts governor Mitt Romney’s tenure at Bain Capital.

“Although these remarks can have short-term benefits to individual candidates in a primary, they are certain to have a negative effect on the party as a whole and a detrimental impact on the conservative movement,” he added.

Grimm endorsed Romney in October, a move for which he has taken heat from some of the same Staten Island tea party groups that had backed his 2010 bid.

The New York Republican also hit the campaign trail for Romney ahead of Tuesday’s New Hampshire primary.
