The White House and GOP leaders have moved to aggressively pitch the legislation, dubbed the American Health Care Act, which they introduced on Monday and hope to vote on within weeks.

The healthcare bill has been met withintense criticismfrom numerous groups representing doctors and hospitals, as well as the American Medical Association, advocacy group AARP and an internal organization from the American Cancer Society.

Conservative groups such as Americans for Prosperity have also come out against the bill, while groups such as the U.S. Chamber of Commerce and Americans for Tax Reform have backed the GOP effort.

"Republicans seem intent on plowing ahead anyway pretending down is up, left is right, & #Trumpcare is somehow not a catastrophe," Warren argued on Twitter.

"The GOP have convinced people who never agree on ANYTHING docs, hospitals, economists, even insurance companies: #Trumpcare is a disaster."
