On Wednesday House Republican leaders announced a congressional investigation of Planned Parenthood. The announcement came a day after anti-abortion activists released a video of an unsuspecting official from the organization explaining how it provides fetal tissue to researchers.

Some top Republicans and Speaker John A. Boehner said that Planned Parenthood was indulged in selling fetal parts, which is illegal if done with profit motive.

But the US affiliate to the International Planned Parenthood Federation said in a statement that it make no money out of processing and transporting the fetal tissue donated by women who go for abortions.

The officials who has been shown in the video repeatedly kept on saying something similar to two activists posing as biotechnology representatives.

Head of the California-based group responsible for the video, the Center for Medical Progress, appears to have been started relatively recently. He has once worked with another anti-abortion group, Live Action, and he and Live Action's leader, Lila Rose, were familiar to Planned Parenthood affiliates from previous undercover videos.

The release of the video and succeeding House investigation opens a new round of wars against Planned Parenthood that have raged since the Republicans took control of the House four and a half years ago.

But this time Republicans running for president also joined the war, promising to stoke the uproar, as anti-abortion conservatives took to social media to demand action.

Some previous battles provoked backlashes against congressional Republicans and against Mitt Romney, the party's presidential nominee in 2012.
