Republican leaders say they're pushing toward a Senate vote next Tuesday on resurrecting their troubled health care bill.
But they still face an uphill battle for their top-flight legislative priority because of unhappy GOP senators.
And now they face two new complications.
The possible absence of ailing Arizona Republican Sen. John McCain means the measure would fail if just two GOP senators vote against it. More than that have already publicly threatened to do so.
And the nonpartisan Congressional Budget Office says a revised GOP bill would produce 22 million added uninsured people by 2026. That's a huge number that helped scare away Republican support for an initial version of the legislation.
The bill would repeal much of President Barack Obama's 2010 health care law.
