Harris campaign costs for star-studded events on election eve ballooned to over $10M: report

These pricey celebrity events featured Lady Gaga in Philadelphia, Jon Bon Jovi in Detroit, Christina Aguilera in Nevada, James Taylor in North Carolina and Katy Perry in Pittsburgh. While the singers did not receive compensation, the newspaper said officials confirmed that the support staff was compensated.

Part of the higher-than-expected costs came from having to rebuild an entire rally venue in Pittsburgh after the Secret Service said the initial location could not be properly secured, The Times reported.

How Harris spent such an exorbitant amount of money during her compressed campaign has left questions as to where all that cash went. 

"Oprah Winfrey was at no point during the campaign paid a personal fee, nor did she receive a fee from Harpo," the spokesperson said.

The costs ranged from $3,500 to $940,000 per disbursement, with $2.2 million going to a company named Private Jet Services Group, while $430,000 went to Advanced Aviation Team, a charter flight broker.

The Harris campaign is believed to be $20 million in debt, but Harris campaign chief financial officer Patrick Stauffer said in a statement reported by the Times that "there will be no debt" on the upcoming December filings for the campaign and the Democratic National Committee.
