Senate Republicans have said they are delaying their effort to vote on legislation repealing ObamaCare until after the July 4 recess after a number of members said they opposed the current bill.
Senate Majority Leader Mitch McConnell (R-Ky.) told members of the decision on Tuesday, according to a Senate GOP aide.
The news was first reported by CNN.
It appeared GOP leaders faced an almost certain defeat on a procedural vote for the measure that Sen. John Cornyn (R-Texas) earlier on Tuesday said was coming Wednesday.
Several GOP senators had said they would oppose their party on the vote, including Sens. Rand Paul (Ky.), Susan Collins (Maine), Mike Lee (Utah) and Ron Johnson (Wis.).
Many other GOP senators were at a minimum undecided on the vote.
A Congressional Budget Office score on the measure found it would leave 22 million more people without insurance compared to present law over the next decade. The analysis also found that the Senate bill would cause premiums to rise over the next two years, undercutting a GOP argument for the bill.
