Michael Bloomberg, the billionaire mayor of New York City, is spending $1 million on TV ads to promote Democrat Cory Booker in the U.S. Senate race in New Jersey.
Bloomberg spokesman Stu Loeser said the ads were being paid for by Independence USA PAC, the independent-expenditure group to which Bloomberg is the sole contributor. Bloomberg created the PAC a year ago and has donated to members of both parties who share his support for initiatives such as gun control.
The ads, first reported by the New York Times, will air in New York City and Philadelphia.
"Mayor Bloomberg has worked with Mayor Booker for a long time and has seen how he's not someone who views things strictly through a partisan lens," Loeser wrote in an e-mail. "He saw that in Mayor Booker's work with Gov. Christie to improve Newark public schools and with the bipartisan Mayors Against Illegal Guns to take on the gun lobby.
