Anti-abortion groups fear that Democrats taking the majority in the House of Representatives next year will pursue a long-held goal of expanding federal funding for abortion by ending the Hyde Amendment, language barring funding for abortion regularly attached to spending bills.

“The pro-life movement cannot be complacent,” Marjorie Dannenfelser, president of the anti-abortion group Susan B. Anthony’s List, said in a statement Wednesday. “We must be prepared to fight to hold the line on important pro-life policies such as the Hyde Amendment.”
