Washington (CNN) -- The House of Representatives on Saturday night passed a sweeping health care bill by a vote of 220-215.
The House Democrats needed 218 votes to ensure passage of the bill. On Saturday, it appeared the vote would come down to the wire, as the intentions of some conservative Democrats remained unknown.
In the final tally, 219 Democrats voted for the legislation, and 39 voted against it.
Rep. Joe Cao (R-Louisiana) was the only Republican who voted in favor of the bill.
