Investigators Find Gaps in White House Logs of Trump’s Jan. 6 Calls

The House committee investigating the Jan. 6 attack on the Capitol has discovered gaps in official White House telephone logs from the day of the riot, finding few records of calls by President Donald J. Trump from critical hours when investigators know that he was making them.

Investigators have not uncovered evidence that any official records were tampered with or deleted, and it is well known that Mr. Trump used his personal cellphone, and those of his aides, routinely to talk with aides, congressional allies and outside confidants.
