Stupak was to be honored at the annual Campaign for Life Gala of the Susan B. Anthony List for his efforts to get the Stupak amendments toughening up restrictions on abortion funding inserted into the healthcare bill voted on Sunday night.

In an 11th hour negotiation, and refusal by Speaker Nancy Pelosi (D-Calif.) to vote on side bills, Stupak accepted an executive order from President Barack Obama to ensure funds wouldn't be used for abortions.

"By accepting this deal from the most pro-abortion President in American history, Stupak has not only failed to stand strong for unborn children, but also for his constituents and pro-life voters across the country," Susan B. Anthony List Candidate Fund President Marjorie Dannenfelser said in a statement.

"Let me be clear: any representative, including Rep. Stupak, who votes for this healthcare bill can no longer call themselves 'pro-life.' The Susan B. Anthony List Candidate Fund will not endorse, or support in any capacity, any Member of Congress who votes for this bill in any future election."
