Backing for single-payer insurance is growing ahead of the planned introduction on Wednesday of the Medicare for All Act from Senator Bernie Sanders, I-VT.

The latest supporter is Senator Sheldon Whitehouse, D-RI, reports the Miami Herald. He joins senators Cory Booker,D-NJ; Jeff Merkley, D-OR; Kirsten Gillibrand, D-NY; Kamala Harris, D-CA, and Elizabeth Warren, D-MA in supporting the bill, which would create a single-payer national health care insurance system.

In a statement on his website, Whitehouse, a member of the Senate Health, Education, Labor, and Pensions (HELP) Committee, said, “It’s time we had a real conversation about creating a national health plan. That’s why I intend to cosponsor Senator Sanders’ bill. And I’ll continue to explore other ways we can improve health care and lower costs, including adding a publicly operated health insurance option to individual marketplaces, like the one I coauthored with Senators Brown and Franken.”
