The committee reported the contribution to the secretary of state's office on Tuesday. It's the second donation from Whitman, whose net worth was once reported to be more than $1 billion. She gave the committee $150,000 last month.
Whitman announced formation of the committee on Feb. 9.
That includes $500,000 from the fortune he amassed after selling his Silicon Valley company, SnapTrack, which developed global-positioning chips for cell phones.
