California will ask the federal government to allow illegal immigrants to buy Obamacare insurance.

Democratic Gov. Jerry Brown signed a bill on Friday that formally requests a waiver from the Obama administration for illegals to buy coverage on California's state-run Obamacare marketplace. Currently illegals are not allowed to do so.

The bill would require insurers on the exchange to extend coverage to illegal immigrants if the waiver is granted. However, illegal immigrants would not be eligible for subsidies under the law.

Currently about 85 percent of Obamacare enrollees get some type of subsidy to lower the cost of insurance.
