The bills come after the Trump administration asked an appeals court to strike down the entire Affordable Care Act.

The lawmakers want to put into state law some of Obamacare’s rules on insurers, including protections for people with pre-existing conditions and letting kids stay on their parents’ plan up to age 26.

Anya Rader Wallack, who used to run the state’s Obamacare exchange, says the prospect of the high court striking down the law could mean “100,000 Rhode Islanders at least potentially losing coverage.”

“We’ve worked really hard to reduce the uninsured rate in this state,” Wallack said, “and this would essentially roll all of that back.”

If the Supreme Court struck down the law, it would spell the end for Medicaid expansion and federally-funded subsidies for people to buy insurance. According to an estimate from the Urban Institute, 20 million people nationwide would lose their coverage if the high court struck down the law.
