WASHINGTON — House Republicans vented their rage against Planned Parenthood on Friday, voting to block all federal financing for the organization, which they accused of profiting from the sale of aborted fetuses for medical research. It was unclear, however, if the vote would mollify conservative lawmakers who have threatened to force a government shutdown over the abortion issue.

Neither the Planned Parenthood bill, which passed 241 to 187, nor a second anti-abortion measure approved on Friday has any chance of becoming law because of opposition from Senate Democrats and President Obama. But the deep emotion expressed by Republican lawmakers during debate underscored the challenge facing party leaders in the days ahead.

“They say for the purpose of advancing medical research, but we all know that it really — there is no excuse that can possibly be given for the moral bankruptcy of Planned Parenthood,” Representative Jody B. Hice, Republican of Georgia, said in a brief speech. “It’s time to defund this while the investigation occurs.”

Democrats said Planned Parenthood provided crucial health care services to women and men and accused Republicans of engaging in baseless attacks on the organization, with the larger aim of trying to limit a woman’s reproductive choice. Republicans in Congress and in several states have begun investigations into Planned Parenthood.
