Project Veritas’s James O’Keefe crashed a private CNN teleconference. CNN says he may have broken the law.

Over the last few years, Project Veritas has gathered evidence in an effort to prove that CNN slants its coverage to hurt President Trump. In the past, that has meant surreptitiously recording and releasing videos of unsuspecting CNN employees talking about the network’s coverage, as well as releasing leaked tapes of comments made by network executives and staffers in editorial meetings. Last year, the conservative group revealed that a contractor hired by CNN as a satellite uplink technician had been a primary “whistleblower” on the effort.

But on Tuesday, Project Veritas — an organization that has used deceptive tactics in some of its attempts to capture proof of what it says is liberal bias and corruption in mainstream media and government — may have crossed a line. To help promote a new cache of two months of recordings of CNN’s daily morning editorial calls, the group’s founder, James O’Keefe, filmed himself calling in to the network’s 9 a.m. meeting and pressing CNN President Jeff Zucker on the network’s journalistic integrity.

While Project Veritas had previously disseminated covert recordings of CNN’s daily meeting, in this video O’Keefe himself could be seen dialing in to a private CNN call — apparently without the knowledge or consent of participants.
