Sen. Lisa Murkowski (R-AK) on Tuesday announced she opposes a plan to repeal Obamacare and delay its replacement.
"No," she said when asked if she backs the idea, according to The Hill. "I said back in January that if we're going to do a repeal there has to be a replacement."
"There's enough chaos and uncertainty already," added Murkowski, the third Republican senator to reject the strategy.
Sens. Susan Collins (R-ME) and Shelly Moore Capito (R-WV) also reportedly said earlier Tuesday they will not support the plan.
Senate Majority Leader Mitch McConnell (R-KY) could only afford two defections on the plan, meaning it now lacks the support to clear the upper chamber.
McConnell on Monday said the Senate would vote to take up the House's Obamacare repeal plan with a two-year delay for replacing the controversial health care law.
The move effectively gave Senate Republicans the chance to repeal Obamacare now, and then delaying a substitute until after the 2018 midterm elections.
Trump is ready to "let ObamaCare fail."
Trump vowed to continue working to reform health care Tuesday morning on Twitter.
Sens. Mike Lee (R-UT) and Jerry Moran (R-KS) announced Monday night that they will not support the GOP's healthcare bill, effectively killing it due to a lack of Senate votes.
The two senators tweeted that they will not support the bill and released press statements to address their concerns.
Moran said in his statement that the GOP bill “fails to repeal the Affordable Care Act or address healthcare’s rising costs.”
“We must now start fresh with an open legislative process to develop innovative solutions that provide greater personal choice," he added.
Lee said the bill does not go far enough to repeal Obamacare.
“In addition to not repealing all of the Obamacare taxes, it doesn’t go far enough in lowering premiums for middle class families; nor does it create enough free space from the most costly Obamacare regulations,” he said in his statement.
Lee and Moran joined two other Republican senators, Rand Paul (R-KY) and Susan Collins (R-ME), in opposing the bill. Senate Majority Leader Mitch McConnell (R-KY), who has been leading the charge on the revised healthcare bill, needed 50 of 52 GOP votes to advance the bill for open debate in the Senate.
McConnell said in a statement that Senate Republicans will now move to repeal Obamacare and replace it at a later date. He called for "a repeal of Obamacare with a two-year delay to provide for a stable transition period to a patient-centered health care system."
