A House measure to keep the health care reform bill from covering abortion was rejected Thursday night-- by one vote.
The provision was voted down in a second House committee vote, just hours after it passed a panel vote.
The amendment said the healthcare bill could not impose requirements for coverage of abortion -- except in limited cases.
The Energy and Commerce Committee approved it in an initial vote, with conservative Democrats and Republicans supporting it.
But committee chairman Henry Waxman later invoked House rules to bring up the amendment for a second vote.
During that time, two conservative Democrats changed their votes. The panel hopes to finish work on the measure, Friday.
