Three key conservative GOP senators are announcing their opposition to health care plans emerging in the House.

Sens. Mike Lee of Utah, Rand Paul of Kentucky and Ted Cruz of Texas say they will oppose "Obamacare Lite" — as some are now dubbing House leadership-backed plans to remake the Affordable Care Act.

Their announcement comes as the two leading conservative coalitions in the House have also come out against the plans.

The opposition from conservatives greatly complicates leadership plans to pass legislation in the House before the Easter holiday that would repeal former President Barack Obama's health law and replace it with a different system built around tax credits, expanded health savings accounts, and high-risk pools.

Leadership insists no final decisions have been made and everything is on track.
