Republicans on Tuesday postponed a vote on a health care reform bill proposed in the US Senate until after the July 4 holiday next week because they are short of votes to pass it. Senate Majority Leader Mitch McConnell told reporters that Republicans in the Senate were still working on making changes to the the bill to make it more palatable to those in his party who remain opposed to it. "We will not be on the bill this week, but we are still working toward getting 50 people in a comfortable place," McConnell said. At least five of the 52 Republicans in the upper chamber said they won't vote for the bill in its current form, leaving McConnell short of the majority needed to pass the legislation. No Senate Democrats have voiced their support for the measure. Discussions were expected to move to the White House later Tuesday. Republican caucus members have been invited to a meeting with President Donald Trump to discuss the legislation, McConnell said, adding that people at the White House are "very anxious to help." Trump has made repealing the so-called Obamacare health care reforms enacted under his predecessor a top priority. The lower House of Representatives passed legislation to do so last month.
