Gov. Chris Christie says he'll leave it to the federal government to establish a state health insurance exchange allowing uninsured residents to shop for affordable health care coverage online.

The governor vetoed legislation Thursday that would have let New Jersey run its own exchange to comply with the Affordable Care Act.

The Republican says there have been too few answers about how much a state-run exchange would cost or who would control it.

States have until mid-December to decide whether to run their own exchanges. They also have the option of partnering with the federal government or letting the feds run the program.

The exchanges are an important provision in the national health overhaul sometimes referred to as "Obamacare."

Christie says it's safest to leave the exchanges up to federal government.
