House Democrats are launching an official Medicare for All Caucus in an effort to promote a single-payer health care bill. The caucus, which was officially announced on Thursday, comes as an increasingly larger number of Democrats warm to the idea. The idea, championed by Sen. Bernie Sanders (I-VT), is now favored by many potential 2020 Democratic presidential contenders. The caucus will launch with about 60 members and will be led by Democratic Reps. Pramila Jayapal (WA), Debbie Dingell (MI) and Keith Ellison (MN), with more expected to sign on in the coming weeks.
