The senator says a final health care bill will end an anti-trust exemption that Durbin says allows insurance companies to legally fix prices.

"We're gonna start watching them more closely and requiring them to spend a higher percentage of premiums collected for actual medical care. The party's over," said Durbin.
"They see a bill that cuts Medicare by half a trillion dollars, that raises taxes by half a trillion dollars, and that almost certainly will raise the cost of insurance for those on the individual market," said Sen. Mitch McConnell, Republican minority leader.
Pres. Barack Obama's goal is to pass a health care bill by March 18.
