The presidential campaign of former House Speaker Newt Gingrich has hit another snag.
   
On Tuesday, fundraising director Jody Thomas and fundraising consultant Mary Heitman left his campaign. This latest blow to Gingrich's 2012 bid comes after 16 top campaign staffers resigned earlier this month.
    
People familiar with the GOP candidate say his fundraising has been troubled since he launched his bid for the White House. His campaign is currently more than $1 million in debt.
      
Ever optimistic, Gingrich insists he will stay in the race "no matter what it takes."

"Newt 2012 continues its reorganization and alignment as a grassroots driven, substantive, solutions-oriented campaign," a spokesman, R.C. Hammond, told The Associated Press, adding that the campaign is "as committed as ever."
