Newt Gingrich’s campaign staffers return

Months after several staffers from former House Speaker Newt Gingrich's presidential campaign left the candidate for greener pastures, some are returning now that Gingrich is surging in the polls:

"It's good to have some old friends come back," R.C. Hammond, spokesperson for the Newt Gingrich campaign, told ABC News about the return of two former Iowa staff members.

The returning staff members are Craig Schoenfeld and Katie Koberg, who left the campaign in June among the mass exodus of two national advisers and several other Iowa staff members.

"What you've seen over the past six months is Newt establish himself as the smartest candidate, capable of leading, an increase in fundraising, showing he's able to run a national campaign and growth of staff and grassroots efforts in several states where he'll be able to compete in each contest," Hammond said.

Support for Gingrich has surged among Iowa Republicans in recent weeks; Gingrich now leads in the state by double digits, according to a recent Rasmussen poll.
