Gov. Gavin Newsom wants to charge monthly premiums for undocumented immigrants and prevent new enrollees in the program as soon as January.

Gov. Gavin Newsom's office said his spending plan for the upcoming fiscal year will call for requiring all undocumented adults to pay $100 monthly premiums to receive coverage and for blocking all new adult applications to the program as of Jan.

To save $5 billion, the California governor wants to close new enrollment to adults who lack legal status and charge premiums. The Legislature has resisted such changes.
