WASHINGTON (AP) -- Health care legislation heading for the Senate floor will give millions of Americans the option of purchasing government-run insurance coverage, Majority Leader Harry Reid announced Monday, although he stopped short of claiming the 60 votes needed to pass a plan steeped in controversy.

Reid, D-Nev., said individual states would have the choice of opting out of the program.

His announcement was cheered by liberal lawmakers, greeted less effusively by the White House and noted with a noncommittal response by Democratic moderates whose votes will be pivotal.

Sen. Olympia Snowe of Maine, the only Republican to vote with Democrats on health care so far this year, issued a statement saying she was “deeply disappointed” in the approach the Democratic leader had chosen.
