The announcements from Sens. Mike Lee of Utah and Jerry Moran of Kansas left the Republican Party's long-promised efforts to get rid of President Barack Obama's health care legislation reeling. Next steps, if any, were not immediately clear.

Lee and Moran both said they could not support Majority Leader Mitch McConnell's legislation in its current form. They joined GOP Sens. Susan Collins of Maine and Rand Paul of Kentucky, both of whom announced their opposition right after McConnell released the bill last Thursday.

McConnell is now at least two votes short in the closely divided Senate and may have to go back to the drawing board or even begin to negotiate with Democrats, a prospect he's threatened but resisted so far. Or he could abandon the health care effort, which has proven more difficult than many Republicans envisioned after campaigning on the issue for years, and move on to tax legislation, a bigger Trump priority to begin with.

McConnell's bill "fails to repeal the Affordable Care Act or address healthcare's rising costs. For the same reasons I could not support the previous version of this bill, I cannot support this one," said Moran.

Lee said, "In addition to not repealing all of the Obamacare taxes, it doesn't go far enough in lowering premiums for middle class families; nor does it create enough free space from the most costly Obamacare regulations."It was the second straight failure for McConnell, who had to cancel a vote on an earlier version of the bill last month when defeat became inevitable.

Trump had kept his distance from the Senate process, but Monday night's development was a major blow for him, too, as the president failed to rally support for what has been the GOP's trademark issue for seven years — ever since Obama and the Democrats passed the Affordable Care Act. Republicans won the White House and full control of Congress in large part on the basis of their promises to repeal and replace "Obamacare," but have struggled to overcome their deep internal divisions and deliver.

The Senate bill, like an earlier version that barely passed the House, eliminated mandates and taxes under Obamacare, and unraveled an expansion of the Medicaid health care program for the poor and disabled. But for conservatives like Lee and Paul it didn't go far enough in delivering on Republican Party promises to undo Obama's law, while moderates like Collins viewed the bill as too extreme in yanking insurance coverage from millions.

McConnell's latest version aimed to satisfy both camps, by incorporating language by Sen. Ted Cruz of Texas allowing insurers to sell skimpy plans alongside more robust ones, and by adding billions to treat opioid addiction and to defray consumer costs.
