Videotapes of witness interviews that the Democrat-led Jan. 6 congressional committee conducted have vanished, raising concerns for the chairman of the successor House panel that is now examining security failures related to the Capitol riot as well as possible implications for upcoming criminal trials.

"All of the videotapes of all depositions are gone," Rep. Barry Loudermilk, R-Ga., chairman of the House Administration oversight subcommittee, told the "Just the News, No Noise" television show Thursday night.
