WASHINGTON — The searing political conflict over abortion flared anew Wednesday as two Republican-led House committees said they will investigate whether Planned Parenthood is selling organs from aborted fetuses.

House Speaker John Boehner, R-Ohio, criticized the group and said President Obama should condemn and end the practice. Other Republican lawmakers joined in, including some who said Congress should end federal aid to the organization.

The Republican offensive came a day after an anti-abortion group circulated a video it made secretly showing a Planned Parenthood official discussing the disposal of body parts from aborted fetuses.

“When an organization monetizes an unborn child – and with the cavalier attitude portrayed in this horrific video – we must all act,” Boehner said in a brief written statement. He said Obama and Health and Human Services Secretary Sylvia Burwell should “denounce, and stop, these gruesome practices.”

Planned Parenthood, which provides abortions and other reproductive health services, says it legally helps women who want to make not-for-profit donations of their fetus’ organs for scientific research. It says it makes no money by donating the organs to science, and that the video was heavily edited.

“These outrageous claims are flat-out untrue, but that doesn’t matter to politicians with a longstanding political agenda to ban abortion and defund Planned Parenthood,” Eric Ferrero, a spokesman for the group, said Wednesday. He said women donating fetal tissue for research “should be honored, not attacked and demeaned.”

Minutes after Boehner released his statement, the House Energy and Commerce Committee said it would investigate the issue and “get to the bottom of this appalling situation.” Republican leaders on the committee said the video “is abhorrent and rips at the heart.” The House Judiciary Committee plans a review, too.

Rep. Jerrold Nadler of New York, a top Democrat on the judiciary panel, called the upcoming investigations “another witch hunt” by Republicans.

Commercial sale of human fetal tissue is illegal under federal law. Noncommercial tissue donation is allowed if the woman undergoing an abortion gives her consent.

Ferrero said Planned Parenthood guidelines for such procedures are carried out “just like other high-quality health care providers – with full, appropriate consent from patients, under the highest ethical and legal standards, and with no financial benefit for the patient or Planned Parenthood.”

By early Wednesday evening, the White House had not responded to requests for comment.

The video, made covertly last year, was produced by the California-based Center for Medical Progress, which released it in collaboration with several national anti-abortion organizations.

It shows a lunchtime conversation between Dr. Deborah Nucatola, Planned Parenthood’s senior director of medical services, and anti-abortion activists posing as potential buyers for a human biologics company.

Nucatola is heard in the video referring to fetal hearts, lungs and livers and to efforts to retrieve these organs intact rather than crush them during an abortion procedure. She is heard giving a range of monetary estimates.

According to Planned Parenthood, Nucatola “was speculating on the range of reimbursement that affiliates can receive after patients state they wish to donate tissue after a procedure.”
