Facing growing Republican opposition, the US Senate majority leader, Mitch McConnell, yesterday delayed a vote on legislation to repeal the Affordable Care Act, otherwise known as 'Obamacare'.

“We're going to continue the discussions within our conference on the differences that we have... that we're continuing to try to litigate. Consequently, we will not be on the bill this week, but we're still working toward getting at least 50 people in a comfortable place," McConnell said.

He said he was still optimistic about passing Obamacare replacement legislation.
