A federal prosecutor is investigating the alleged hack of internal Fox News video footage of former host Tucker Carlson, as clips have surfaced on Vice and watchdog group Media Matters for America.

The Tampa Bay Times reported that the probe is linked to a recent FBI search of the home of media consultant Tim Burke, who formerly worked for Deadspin and The Daily Beast, and is married to Tampa Bay City Councilwoman Lynn Hurtak.

The Times cited a letter that Assistant U.S. Attorney Jay Trezevant sent to the network, in which he wrote that Fox News was one of the “potential victim-witnesses” of the hacking. Deadline also obtained the letter, dated on Thursday, in which Trezevant wrote that the investigation is of allegations of unauthorized computer access, interception of wire, oral or electronic communication, conspiracy and other federal statutes.

[Interesting. The original Tampa Bay Times report is paywalled, but here’s the link. The TBT reports that the federal prosecutor looking into the hacking of Fox News and Tucker Carlson’s show sent Fox a letter late last week that they had made progress on their probe. Two sources confirmed that the raid on Burke and Hurtak related directly to the hacking investigation. Awful Announcing reported on Friday that Burke’s media consulting and training business has been off-line since the raid on May 8, too. — Ed

Update: I erroneously cited this as Deadspin rather than Deadline. I’ve fixed it now. — Ed]
