High-ranking Democratic Sen. Patty Murray has laid out proposals for helping to stabilize Obamacare’s exchanges that would involve injecting billions of federal dollars into the market so that premiums don’t rise as much as initial requests show.

Murray, D-Wash., pointed to proposals made by other Senate Democrats, including a provision that would allow people who live in counties with no Obamacare insurer to purchase the same coverage as Congress and another that calls for a reinsurance program. Though she didn’t specify how much to spend on the program, which would help lower premiums for people who don’t receive subsidies under Obamacare, previous programs that the law set up for a limited period of time allocated $10 billion in 2014, $6 billion in 2015 and $4 billion in 2016.
