Bernie Sanders: GOP health care bill 'most harmful' ever

"It should tell you something that major, major legislation is being written at this moment, and most Republicans don't have a clue as to what's in that legislation, let alone Democrats, let alone the average American", Sanders noted in a speech on the Senate floor late Monday.

U.S. Senator Joe Manchin (D-W.Va.) is still willing to work on fixes for the Affordable Care Act, also known as Obamacare. But its fate remains uncertain.

The announcement comes after Senate leadership released the legislative language of its version of the American Health Care Act, which turned out to be similar to the House-passed version of the bill, despite some rhetoric pointing to an overhaul.

The four are Ted Cruz of Texas, Ron Johnson of Wisconsin, Mike Lee of Utah and Rand Paul of Kentucky.

"I mean, if you don't have insurance and you have a chronic disease and you can't afford your prescription drugs, you know what, you're gonna die, you'll become much sicker", he continued.

The four say there are provisions that are an improvement to the current health care system.

"No matter what back-room deals senators make in the coming days, there is no way to fix this shocking and cruel bill", said Anna Galland, executive director of MoveOn.org about the GOP health care bill.

"I look forward to examining this new proposal carefully and reviewing the analysis by the Congressional Budget Office when it is available. This is the most anti-working class legislation that I've ever seen". If not, I will oppose it.

"I don't care what your political view is".
