Agents from the California Department of Justice raided the home of an indicted anti-abortion activist and seized undercover videos allegedly showing Planned Parenthood officials arranging to illegally sell fetal tissue for profit, the activist said late Tuesday. 

David Daleiden, the founder of the Center for Medical Progress, which released the videos, said in a Facebook post that agents had "seized all video footage showing Planned Parenthood's criminal trade in aborted baby parts, in addition to my personal information."

Daleiden added that the agents left behind documents that he contends implicate Planned Parenthood in illegal behavior related to the handling of fetal tissue.

Center for Medical Progress spokesman Peter Robbio told the Associated Press the social media posting was authentic, but he declined further comment. He said Daleiden lives in Orange County, Calif.

Rachele Huennekens, a spokeswoman for state Attorney General Kamala Harris, said in an email that she can't comment on any ongoing investigation.

Harris said in July that she planned to review the undercover videos to see if center violated any state charity registration or reporting requirements. She said that could include whether Daleiden and a colleague impersonated representatives of a fake biomedical company or filmed the videos without Planned Parenthood's consent.

Harris, a Democrat, is running for the U.S. Senate. Daleiden suggested in the social media posting that the raid was politically motivated because Harris has accepted campaign contributions from Planned Parenthood.

Daleiden faces related charges in Texas. One of his Texas attorneys, Terry Yates, did not return telephone and email messages Tuesday.

Texas authorities initially began a grand jury investigation of Planned Parenthood after the undercover videos were released in August.

But the grand jury cleared Planned Parenthood of misusing fetal tissue and indicted Daleiden and a colleague, Sandra Merritt, in January on charges including using fake driver's licenses to get into a Houston clinic.

Daleiden previously said his group followed the law in making the videos. His post Tuesday called the raid an "attack on citizen journalism" and said he will "pursue all remedies to vindicate our First Amendment rights."

Matt Heffron, a former federal prosecutor and a legal adviser to Daleiden, said the raid was "outrageously out of proportion for the type of crime alleged. It’s a discredit to law enforcement [and] an oppressive abuse of government power."
