The Vermont senator slammed the GOP plan for its content, its secrecy, and the fact that there have been zero committee hearings on the legislation - unprecedented for a bill of this magnitude. But when you encounter problems, he said, "sometimes you need to go behind closed doors to work it out".
"There's only one reason why Republicans are doing this: They're ashamed of their bill", said Schumer on Monday.
A senior Democratic aide told CNN earlier Monday that Democrats plan to object to routine requests to let the chamber operate, including its scheduling votes or allowing committees to meet for extended hearings, a move aimed at escalating the fight over health care.
The aide said Democrats will begin slowing work on bills by refusing to let the Senate bypass time-consuming procedural steps, which it customarily does on most legislation.
McConnell is using closed-door meetings among Republicans to write the bill.
Perhaps in anticipation of the maneuvering led by the New York Democrat, Senate Majority Leader Mitch McConnell of Kentucky had already lined up procedural votes by moving to limit debate on a pair of President Donald Trump's nominees for key positions at the Treasury Department.
There were private talks between Reid and then-House Speaker Nancy Pelosi, D-Calif., after the late Sen.
As the revved up Sanders alluded to in his floor speech, Republicans are terrified of being transparent about this legislation because they know the American people will reject it.
The GOP-run House narrowly approved its version of the legislation last month.
What's more, the Congressional Budget Office estimated that the House health care bill would result in 23 million fewer people with insurance in a decade, and it would leave many sicker and older Americans with much higher costs.
McConnell answered both times: "I think we'll have ample opportunity to read and amend the bill". He said his group is targeting 11 Senate Republicans, including Bill Cassidy of Louisiana, Dean Heller of Nevada, Rob Portman of OH and Collins and Murkowski. The initial House bill was posted online for 30 days before the first of three committees began voting on the measure, and the Senate spent 25 days debating health care overhaul.
Republicans fired back shortly afterward with a release titled, "Does All-Out War Sound Bipartisan?" listing quotes from Schumer and other Democrats promising to do everything they can to defeat the emerging GOP measure.
