Sen. Bernie SandersBernie SandersThe Hill's 12:30 Report: Next steps in the Trump impeachment Sanders selling sweatshirts with his famous inauguration pose for charity Former Sanders spokesperson: Biden 'backing away' from 'populist offerings' MORE (I-Vt.) said that it is “unprecedented” in the history of modern America for legislation as massive as the Senate GOP's healthcare overhaul to be written and discussed entirely behind closed doors without any input from the minority party.

“We’re talking about, in terms of healthcare, one-sixth of the American economy — trillions of dollars,” Sanders told MSNBC Monday night, shortly after speaking against the bill on the Senate floor. “We’re talking about an issue that impacts virtually every single American in our country."

Democrats took over the Senate floor on Monday to protest the GOP's closed-door effort. Republicans are expected to force a vote on legislation as soon as next week.

“In the midst of all of this, you have a process by which right now perhaps a dozen Republicans are the only people in America who know what is being talked about, what the new bill might look like,” Sanders said. “Most Republicans don’t even know it, let alone anybody in the Democratic caucus.” 

Sanders pledged to "do everything humanly and legally possible" to make sure the GOP bill "never sees the light of day."
