The top Republican on the Senate Finance Committee has called for an investigation of Planned Parenthood, following the release of a second video showing a top official discussing compensation for aborted fetal body parts.

Sen. Orrin Hatch of Utah said Wednesday he's "horrified" by the video and wants Congress to investigate the group, which provides healthcare and abortions for women.

"I am horrified by the videos showing Planned Parenthood officials discussing the sale of unborn baby parts as casually as a mechanic might seek to sell car parts," Hatch said in a statement. "While this particular display of callous disregard for human life may shock us, it should come as no surprise amid a culture that does so little to protect those who are most vulnerable — the unborn."

Two House panels are already investigating the group, but Hatch stopped short of announcing any third investigation by his own committee.

Republicans are outraged over two videos released by an anti-abortion group called the Center for Medical Progress, which went undercover to obtain footage of top Planned Parenthood officials discussing how some clinics collect and donate aborted fetal tissue for medical research.

Planned Parenthood says it has done nothing illegal, but abortion foes are charging that it illegally sold fetuses for a profit and violated patient standards of care to obtain intact fetal organs.
