4 Republican senators say they cannot support health care bill

WASHINGTON, June 22 (Reuters) - Four conservative U.S. Republican senators said on Thursday they are not prepared to vote for the Senate Republican health care proposal unveiled on Thursday when it comes to the floor, probably next week.

"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 senators -- Rand Paul, Mike Lee, Ron Johnson, and Ted Cruz -- said in a joint statement. The draft bill would not repeal Obamacare and lower healthcare costs, they said.

If legislation is to prevail, Republicans can only lose the support of two of the Senate's 52 Republicans, assuming all 48 Democrats and independents oppose the bill as expected.
