The Senate health-care bill got new obstacles late Monday, after Republican Sen. Susan Collins of Maine said she would vote against allowing the bill to go forward. Collins’ opposition came after another Republican, Sen. Dean Heller, was skewered by Trump supporters for coming out against the bill on Friday. Several other Republican senators have expressed concerns about the bill, even as Senate Majority Leader Mitch McConnell pushes for a vote by July 4. Collins announced her stance after the Congressional Budget Office concluded that 22 million Americans would lose coverage under the new plan. Noting that she wants to “fix the flaws” in the Affordable Care Act, Collins said the CBO’s report shows the “Senate bill won’t do it.” “I will vote ‘no’ on moving to proceed,” she said. Sens. Rand Paul of Kentucky, Ted Cruz of Texas, Ron Johnson of Wisconsin, and Mike Lee of Utah have also come out against the bill.
