An anti-abortion group on Tuesday released a second video it said showed that Planned Parenthood sells aborted fetal tissue, repeating allegations raised last week in a video that quickly spurred government investigations.

Both secretly recorded videos were produced by the Center for Medical Progress in California with actors posing as buyers for a biological company. They feature interviews with different officials at the non-profit reproductive health organization, with edited excerpts appearing in the versions widely circulating online.

“Planned Parenthood’s top leadership admits they harvest aborted baby parts and receive payments for this," said the group's leader, David Daleiden, in a statement on Tuesday.

Planned Parenthood Federation of America said in a statement "the video was heavily edited in attempt to support false and outrageous claims," and it denied any improper activity.

The organization has said it does not profit from fetal tissue donation and only receives payment for associated costs, which is legally permissible.

In a letter sent to Congress on Monday, Planned Parenthood said Daleiden was a longtime anti-abortion activist and questioned the legality of his practices.

Planned Parenthood also said in the letter to the chairman of the House Energy and Commerce Committee, which last week launched an investigation into the claims in the video, that more videos could surface.

"These videos are part of a decade-long campaign of deceiving the public, making false charges, and terrorizing women and their doctors, all in order to ban abortion and cut women off from care at Planned Parenthood," spokesman Eric Ferrero said in a statement.

Multiple committees in the Republican-led U.S. Congress have launched investigations. Planned Parenthood is also being probed at the state level by several Republican governors and other leaders.
