A key legislative committee in California has revived a bill that would create a government-run health care system in the nation's most populous state.

The Senate Appropriations Committee released the bill Thursday for a vote by the full Senate next week. The legislation had been held over from last year.

Creating a single-payer system would cost an estimated $210 billion in its first year. That's roughly double the size of the total state budget.

The bill by Sen. Mark Leno, D-San Francisco, would create a commission to decide how to pay for it.

Republicans mocked majority Democrats for reviving the bill two days after Massachusetts voters elected a senator who opposes the Obama administration's national health care plan.
