Joining forces with U.S. Sen. Bernie Sanders of Vermont, Sen. Sheldon Whitehouse is the latest lawmaker to announce plans to co-sponsor legislation to create a single-payer health system.

The “Medicare for All” legislation, slated to be introduced in the Senate Wednesday, aims to guarantee health coverage for all Americans.

U.S. Sen. Elizabeth Warren, Democrat from Massachusetts also is backing the bill.

“Everyone is covered,” Warren said in a blog post announcing her support of the bill. “Nobody goes broke paying a medical bill. Families don’t have to bear the costs of heartbreaking medical disasters on their own.”

The legislation comes after several failed attempts by Republicans to repeal the Affordable Care Act, the signature Obama era legislation that expanded Medicaid, the government insurance program for low-income people, and guaranteed health coverage for people with preexisting conditions.
