"Robert Mueller’s report lays out multiple examples of ways the investigation was “impaired,” either by lying witnesses or by successful deletion of key conversations. “Several individuals affiliated with the Trump Campaign lied to the Office, and to Congress, about their interactions with Russian-affiliated individuals and related matters,” the redacted report reads. “Those lies materially impaired the investigation of Russian election interference.” The impairments cover alleged lying by witnesses, including the well-known cases of Michael Flynn, Michael Cohen, and George Papadopoulos. But they also cover cases where Mueller was hindered by deletion of data on encrypted apps, or by the simple fact that the target was located outside the United States, as the redacted report lays out in detail."
