'Medicare for all,' Stabenow says

Many liberal lawmakers backed the single-payer plan during initial debates over healthcare reform, and Obama praised the idea on the campaign trail in 2008. The Affordable Care Act did not create that system and did not include a "public option." 

Stabenow hammered opponents of the healthcare law and ongoing attempts by the GOP to obstruct it. "I'm tired of the fights about whether or not it should exist. It does exist. It's changing lives," she said.
