A defiant California Gov. Arnold Schwarzenegger vowed to veto a budget passed by California lawmakers early Tuesday after a record 78-day impasse, saying legislators had failed to incorporate needed reforms to deal with the state's fiscal problems.

The threat by Gov. Schwarzenegger, if he follows through, would be the first time a California governor has ever vetoed an entire budget, though it isn't likely to prevent the spending plan from going into effect. State leaders from the Democrat-controlled legislature said they were confident they had enough votes to override a veto.

Still, a bigger showdown appears to be brewing between the governor and state lawmakers. Gov. Schwarzenegger threatened further vetoes of "hundreds" of other bills awaiting his approval to put pressure on lawmakers to enact reforms. "The budget they passed this morning takes our problems and makes them even worse," he said at a news conference.

Karen Bass, the Democratic speaker of the California assembly, said she was about "95% certain" that lawmakers would be able to muster the two-thirds majority necessary to override the governor's veto. The bill passed 28-12 in the state Senate and 61-11 in the Assembly.

The stalemate over the state's budget was at risk of deepening a fiscal crisis, causing layoffs, hiring freezes and reduced wages for state employees.
