A wide array of corporations also poured money into the event. Philadelphia-based Comcast was the largest donor, giving $5.6 million, mostly through in-kind contributions of staff, advertising and hardware. David L. Cohen, a top Comcast executive, served as a senior adviser to the committee. Cohen has been a top fundraiser for President Obama and has helped raise money for Democratic presidential nominee Hillary Clinton.
Other major corporate donors included PECO Energy Co. ($1.8 million), Independence Blue Cross ($1.5 million), Facebook ($1.45 million) and Bank of America ($1 million).
Only two individuals broke the million-dollar mark: J.B. Pritzker, a Chicago-based investor and philanthropist, who donated $1.25 million; and H.F. Lenfest, the former owner of the Philadelphia Inquirer and Daily News, who gave $1 million.
Money also flowed from the pro-Clinton Priorities USA Action, which helped out with $1.5 million.
Some of the donors were not immediately identified. About $4.5 million came to the host committee through the Philadelphia Convention & Visitors Bureau, a workaround that officials created after the host committee failed to obtain its designation as a charity under section 501(c)(3) of the tax code. A spokeswoman for the bureau said that three contributors were willing to have their names disclosed: the Greater Philadelphia Chamber of Commerce ($10,000), the Drumcliff Foundation ($50,000) and the Dyson Foundation ($125,000).
For its part, the host committee for the Republican National Convention in Cleveland raised more than $65 million in cash and in-kind donations, with major sponsors including AT&T (nearly $4.3 million), Microsoft ($1.8 million in software), Jones Day ($1.5 million) and oil interests such as Marathon Petroleum ($1.2 million).
