The minor controversy, relative to the major controversies already swirling around the former President, of the deleted Secret Service messages of January 6, 2020, suggests a management misstep. If the content of text messages, or other similar material, could be threatening to the status of the generators or their bosses, the existential status of that material should not be under the control of the same personnel. It should be under the control of a neutral third-party who must adhere to anti-corruption regulations and/or statutes.
I hope that was dry enough for you.
