WASHINGTON – Four Republican senators from the conservative wing of their party say they oppose the Senate health-care bill as it was introduced by Senate Majority Leader Mitch McConnell on Thursday, which places the effort to overhaul the American health-care system in jeopardy as it heads for an anticipated vote in the Senate next week. Those senators – Rand Paul of Kentucky, Ted Cruz of Texas, Ron Johnson of Wisconsin and Mike Lee of Utah – released a statement stating that while they cannot support the bill as its currently written, they are open to negotiating changes that could ultimately win their support. “Currently, for a variety of reasons, we are not ready to vote for this bill, but we are open to negotiation and obtaining more information before it is brought to the floor,” the statement read.
