The sum is only a fraction of the roughly $17 million Brown had on hand as of Dec. 31. But it is more than twice what Tim Donnelly, the other Republican in the race, raised all of last year.
Kashkari's campaign announced Wednesday that the former U.S. Treasury Department official had raised $976,000 since announcing his candidacy last month. Kashkari has filed campaign statements showing contributions of just under $915,000. The campaign said the balance consists of checks less than $5,000 that are not yet required to be reported.
Former Treasury Secretary Henry Paulson and his wife, Wendy, each contributed $27,200, as did billionaire Robert Day, chairman of Trust Company of the West, and each of Kashkari's parents, Chaman and Sheila. Slightly more than two-thirds of the total amount raised came from California donors. Many of the contributors are members of the financial industry, including employees of Goldman Sachs, where Kashkari previously worked.
Kashkari raised fundraising expectations by saying before he announced his candidacy that he had met with hundreds of potential donors, and his campaign promoted his earnings in a news release just before filing contribution reports with the state.
In an online video, Kashkari said the contributions reflect an "outpouring of support."
Donnelly, a Twin Peaks assemblyman, raised less than $375,000 in 2013 and ended the year with only $54,299 in cash on hand. Former Lt. Gov. Abel Maldonado dropped out of the race last month after raising just $517,772 last year.
Brown has not yet said if he will seek re-election, but he is widely expected to run.
