Whitman adds $13 million to coffers, approaches record spending

California billionaire Meg Whitman (R) has dropped another $13 million into her campaign for governor. 

The contribution brings the former eBay CEO's investment in her bid to $104 million, the Sacramento Bee reported. Her personal spending is approaching the record set by fellow billionaire Michael Bloomberg in 2009.

The New York City mayor spent some $108 million in winning a third term last year.

Whitman's camp said the money was needed to "fight" Democrat Jerry Brown's "attacks."

"Meg is investing the necessary resources to fight the $13 million in attacks Jerry Brown Inc. has launched to defend the status quo in Sacramento," Sarah Pompei, a spokeswoman for Whitman told KQED. "She will continue discussing her plans to create jobs with Californians across the state."

Brown had $23 million in the bank as of June 30. 

Meanwhile, Whitman was attacked for being part of a "job destruction duo" along with Republican Senate candidate Carly Fiorina by a top union official Friday.

"Some people see public employees as an island of privilege," AFL-CIO President Richard Trumka said in a speech in Los Angeles. "The truth is you're the foundation of decent standards; you're the only ones standing in the way of a Republican-driven, all-out race to the bottom."
