Alabama Sen. Richard Shelby took to the Senate floor Tuesday to blast health care reform being debated in the Senate right now.
Democrats say they hope to have it passed and on the president's desk by the end of the year.
Republicans and some Democrats have voiced concerns, though, over the bill's cost, and how it might affect those who already have insurance.
Shelby says the current bill is not acceptable.
"Supporters of government-run medicine often cite Canada or Great Britain as models for the U.S. to follow. Yet medical rationing, such as is common in these countries, is inevitable under a government-run health care system," said Shelby. "These countries are forced to ration care or have long waiting lists for medical treatment that lead to the same result."
A different health care bill has already passed the U.S. House of Representatives.
