Bernie Sanders is getting some serious support in his push to reform the US healthcare system.
Sanders on Wednesday will roll out a Medicare-for-all bill, which aims to extend the Medicare program, federally funded insurance for people over the age of 65, to all Americans.
A single-payer healthcare push has previously been well outside the mainstream for most Democrats. But Sanders' legislation has picked up support from high-profile Democrats.
The latest Democratic senator offering support is Kirsten Gillibrand of New York.

Sen. Cory Booker of New Jersey also offered support for Sanders' legislation this week.
"I'm signing onto Medicare-for-all, which I'm excited to do this week," Booker said in an interview with NJTV on Monday. "Sen. Sanders, myself, and some others are going to be announcing some legislation this week along with some of my other colleagues."
Booker, who has been floated as a possible contender for the Democratic presidential nomination in 2020, said Obamacare was just a "first step" in securing healthcare for all Americans.
