A high-ranking Senate Democrat who supported President Obama's health care overhaul now says it's a disaster in the making.

Finance Committee Chairman Max Baucus grilled Health and Human Services Secretary Kathleen Sebelius at a Senate budget hearing Wednesday.

Baucus cited concerns that new health insurance marketplaces for small businesses and consumers won't be ready in time in every state. Those marketplaces are supposed to be up and running next year.

Baucus also said consumers don't have the information they need to make good choices.
   
"I just see a huge train wreck coming down," Baucus said.

Sebelius says implementation of the exchanges is on track. She blamed congressional Republicans for hampering progress by denying funds for Obamacare.
