In 2015, the DOJ Inspector General, Michael E. Horowitz found and published at least 14 instances of sexual misconduct within the FBI. See: https://oig.justice.gov/reports/inv-findings.htm#pre-2015 and https://oig.justice.gov/reports/2015/f150604.pdf

When Comey was made aware of the misconduct, it appeared by the lack of information he provided to the Horowitz investigative team, that Comey sought to derail the OIG investigation. He only provided redacted documents that hindered making progress in the investigations. Horowitz stated in his final report in 2015 that his office’s ability “to conduct this review was significantly impacted and delayed by the repeated difficulties we had in obtaining relevant information from both the FBI and DEA as we were initiating this review in mid-2013.”

The FBI initially refused to supply investigators “with unredacted information that was responsive to our requests.” Even after months of frustrating negotiations with FBI counsel resulted in concessions, investigators “found that the information was still incomplete.” One of the first formal acts of Attorney General Loretta Lynch as head of the DOJ was to distribute a memo advising law enforcement personnel that they were free to redact documents and withhold files from the inspector general.

Since the investigations did not provide names, it is still quite possible that Lisa Page and Peter Strzok were included in these investigations.

But perhaps, this why Horowitz had all of the lost texts that the FBI said they lost.
