Deal ‘s official report is due to be submitted later tonight to the Georgia Government Transparency and Finance Commission.
But Brian Robinson, Deal’s chief of staff, confirmed the $550,000 figure.
The money includes an estimated $200,000 the GOP governor collected at a June 16 reception in Savannah.
Nearly all of the $550,000 was rounded up after April 14, after the General Assembly adjourned.
Candidates for state office are barred from accepting campaign money during the session, which began Jan. 10, the day Deal was sworn in.
Experts say a strong early fundraising effort by new office holders gives them a leg up over potential challengers and may even discourage some from emerging.
