A leading abortion rights advocate in the House said on Saturday that as many as 50 lawmakers were prepared to abandon health care reform legislation if the final bill were to include more restrictive abortion language.
Rep. Jan Schakowsky (D-Ill.) told reporters that she has conveyed to House Speaker Nancy Pelosi that she and at least 49 other pro-choice Democrats would vote against the final measure if abortion language authored by Rep. Bart Stupak (D-Mich.) were to be reinserted.
“She knows that,” Schakowsky said, “and the Speaker is pro-choice herself. She has made it very clear to Bart Stupak that there is no deal. But he can’t seem to take yes for an answer.
