From the Washington Post:

House leaders were working to secure their votes late Saturday with the promise of an executive order affirming President Obama’s commitment to a longstanding ban on public abortion funding except in cases of rape or incest, or to save the life of the mother. Rep. Marcy Kaptur (D-Ohio), a key antiabortion vote, said she thought the document would be insufficient to bring the entire group of about 10 antiabortion Democrats onboard.
