A new study says the Republican plan to repeal the President's health care law risks making nearly 30 million people uninsured.

FOX's Jon Decker has more from the White House:

The new analysis by the nonpartisan Urban Institute warns that repealing major parts of the Affordable Care Act without a clear replacement could upend the health insurance market for people buying their coverage through Healthcare.gov.

Republicans say that won't happen because of their strategy to repeal major portions of the ACA next year, with the stipulation that the effective date of that repeal would be delayed by months or years to give lawmakers time to write replacement legislation.

The study found that about 30 million people would lose coverage due to repeal of the law's subsidies, Medicaid expansion and its individual requirement to carry health insurance.
