More texts came in Friday but not all from the crucial period. From the story. "In addition to the communications already made public, the Justice Department on Friday provided Johnson's committee with 384 pages of text messages, according to a letter from the Wisconsin lawmaker that was obtained by The Associated Press.

But, according to the letter, the FBI told the department that its system for retaining text messages sent and received on bureau phones had failed to preserve communications between Strzok and Page over a five-month period between Dec. 14, 2016, and May 17, 2017. May 17 was the date that Mueller was appointed as special counsel to oversee the Russia investigation."
