Bernie Sanders headlining 'don't take our health care' rallies in three states

The events are aimed at pressuring GOP senators to oppose the bill.

Sanders teamed up with progressive advocacy organization MoveOn.org to hold rallies this weekend in Pittsburgh; Columbus, Ohio; and Charleston, West Virginia, with the goal of pressuring Republican senators in each of the states to oppose the legislation released Thursday.

Five GOP senators have so far announced their opposition to the bill drafted by some of their Republican colleagues. Republicans can afford only two defections from the 52 senators in their ranks to pass the bill.

Sanders has slammed the legislation as "disastrous," saying in a statement Thursday that it "has nothing to do with health care. It has everything to do with an enormous transfer of wealth from working people to the richest Americans."

Sanders spokesperson Josh Miller-Lewis told ABC News, “We’re at a pivotal moment in the fight to save health care and the goal this weekend is to elevate that fight.”

The first rally is tonight at 7 p.m. in Pittsburgh, followed by events Sunday in Ohio and West Virginia.
