Charles Thorley, the acting assistant director of the FBI’s office of congressional affairs, wrote in a letter this week to Senate Judiciary Chairman Chuck Grassley, R-Iowa, that FBI employees are “required to adhere to record keeping policies in place where communications constitute records under the Federal Records Act.”

He added in the letter that “the FBI is not otherwise obligated to collect and/or retain all communications between its employees.”

“Thus, the FBI has not requested from Ms. Page or Mr. Strzok any information from their personal email accounts, nor as the FBI conducted searches of non-FBI-issued communications devices or non-FBI email accounts associated with Mr. Strzok or Ms. Page,” he said.
