"This is our opportunity to really make a difference on health care", said Senate Majority Leader Mitch McConnell, who tried to get fellow Republicans to at least begin debate in the full Senate on the plan next week.
"It is hard to expect people to be as productive as they should be when they don't have basic health care", Leffler said.

GOP leaders unveiled the Senate's revised health care bill on Thursday, and the updated legislation included a version of a controversial amendment drafted by Sen. The two chambers would have to eventually agree on a common piece of legislation to successfully repeal and replace the ACA.
In particular, Democrats and left-leaning Republicans strongly criticised moves to include a version of a proposal by Republican senator Ted Cruz that will allow insurers to sell plans that don't comply with the Obamacare requirements if they also offer plans that do.
"You want to keep your mandates?" This latest version adds $70 billion to a fund for states - bringing the total to $132 billion - to help support coverage of low-income people.

A vote on the measure is possible next week. Paul against the effort puts Senate Republican leadership in a tough spot - they need approval votes from 50 of the 52 GOP senators.
