Internal White House records from the day of the attack on the U.S. Capitol that were turned over to the House select committee show a gap in President Donald Trump’s phone logs of seven hours and 37 minutes, including the period when the building was being violently assaulted, according to documents obtained by CBS News’ chief election & campaign correspondent Robert Costa and The Washington Post’s associate editor Bob Woodward. The lack of an official White House notation of any calls placed to or by Trump for 457 minutes — from 11:17 a.m. to 6:54 p.m. — on Jan. 6, 2021 means there is no record of the calls made by Trump as his supporters descended on the U.S. Capitol, battled overwhelmed police and forcibly entered the building, prompting lawmakers and Vice President Mike Pence to flee for safety. The 11 pages of records — which consist of the president’s official daily diary and the White House switchboard call log — were turned over by the National Archives earlier this year to the House select committee investigating the Jan. 6 attack. The records show that Trump was active on the phone for part of the day, documenting conversations that he had with at least eight people in the morning and 11 people that evening. The gap also stands in stark contrast to the extensive public reporting about phone conversations he had with allies during the attack. The House panel is now investigating whether Trump communicated that day through backchannels, phones of aides or personal disposable phones, known as “burner phones,” according to two people with knowledge of the probe, who, like others interviewed for this report, spoke on the condition of anonymity to discuss sensitive information. The committee is also scrutinizing whether it received the full log from that day. The records show that former White House chief strategist Stephen K. Bannon — who said on his Jan. 5 podcast that “all hell is going to break loose tomorrow” — spoke with Trump twice on Jan. 6. A spokesman for the committee declined to comment. In a statement Monday night, Trump said, “I have no idea what a burner phone is, to the best of my knowledge I have never even heard the term.” A Trump spokesperson said that Trump had nothing to do with the records and had assumed any and all of his phone calls were recorded and preserved.
