California deficit has soared to $16 billion, Gov. Jerry Brown says

Gov. Jerry Brown announced on Saturday that the state's deficit has ballooned to $16 billion, a huge increase over his $9.2-billion estimate in January.

The bigger deficit is a significant setback for California, which has struggled to turn the page on a devastating budget crisis. Brown, who announced the deficit on YouTube, is expected to outline his full budget proposal on Monday in Sacramento.

"This means we will have to go much further, and make cuts far greater, than I asked for at the beginning of the year," Brown said in the video.

Lawmakers and others were hoping that a rebounding economy would help the state avoid steep cuts to social services. But revenue in April, the most important month of the year for income taxes, fell far short of expectations, leading to a shortfall of at least $3 billion in the current fiscal year.

The state has also spent $2.1 billion more than expected, according to the controller, further worsening California's financial health.
