George Washington University law professor and Fox News contributor Jonathan Turley said Monday that the FBI’s investigation into the alleged theft of a diary belonging to President Biden’s daughter’s raises “legitimate concern” over the first family’s connection to the bureau.

The FBI on Sunday raided the home of Project Veritas founder James O’Keefe as part of a federal investigation into the “stolen” diary of President Biden’s daughter, Ashley Biden. The New York Times reported the raid took place early Saturday morning just days after the homes of two Project Veritas associates were also the subject of search warrants.

“Why would the FBI be coming in on this?” Turley asked on “America Reports.” “Project Veritas said it didn’t run the information and notified local enforcement. So there is a legitimate concern when the FBI becomes involved in this type of story, as to whether it is going outside of those navigational beacons that we use to judge whether they are acting independently.”
