Sen. Joe Manchin (D-W.Va.) said Sunday that Obamacare could be headed for a "complete meltdown" if costs rise too fast and people are unhappy with their coverage.

“If it’s so much more expensive than what we anticipated, and if the coverage is not as good as what we've had, you’ve got a complete meltdown at that time,” Manchin said on CNN’s “State of the Union.”

The senator said such a situation would result in the law collapsing under "its own weight."
