WASHINGTON (CBS News) -- Senate Majority Leader Mitch McConnell's plan to vote on a bill from 2015 that would repeal Obamacare with a two-year delay to find a replacement plan died in the Senate Tuesday.
In rapid succession, three Republican senators signaled that they would vote against a motion to proceed on measure: Susan Collins of Maine, Shelley Moore Capito of West Virginia and Lisa Murkowski of Alaska.
"I'm going to oppose the motion to proceed," Collins told reporters. "I voted against this approach in 2015 and I do not think it's going to be constructive to repeal a law that at this point is so interwoven within our healthcare system and then hope over the next two years we will come up with some kind of a replacement. I think that would create great anxiety for individuals who rely on the ACA, I believe it would cause the insurance markets to go into turmoil."
While Sen. Shelley Moore Capito, R-West Virginia, said in a statement, "I cannot vote to repeal Obamacare without a replacement plan that addresses my concerns and the needs of West Virginians," she then made her position even more clear on Twitter.
As Murkowski boarded an elevator at the Capitol, she told reporters she is a "no" on the motion to proceed.
This comes after a second version of the Senate Republican plan to repeal and replace the 2010 health care law hit a dead end late Monday, as two more GOP lawmakers came out against it, effectively blocking the legislation from advancing.
While it's unclear how Republican leaders in both chambers plan to move forward on health care, a number of GOP senators are already calling for bipartisan negotiations. Senate Republicans are huddling behind closed doors for lunch on Tuesday.
