The Democratic governor has not yet said if he will seek re-election but is widely expected to run. He received major funding from labor unions and business interests, including oil and telecommunications companies.
Brown leads a small field of Republicans by a wide margin in early fundraising and polls.
Brown reported spending only about $208,000 in campaign operations last year, with most of that amount coming in the last six months of the year. In addition to various office and fundraising expenses, Brown reported "bonus" payments of $25,000 each to Angie Tate, a Democratic fundraiser, and Edward Ruthrauff, who worked on Brown's 2010 campaign before coming into the administration to be Brown's director of constituent affairs.
Assemblyman Tim Donnelly, R-Twin Peaks, has until the end of the day to file his year-end financial statement. Neel Kahskari, a former U.S. Treasury Department official, did not start fundraising until earlier this month, when he announced his candidacy.
