What appearance of impropriety was he trying to avoid?
I'm sure that trying to hide documents and the dismissed guy from Congress are routine and intellectually honest things as well.
And it's weird that the special counsel charged Flynn for lying but the FBI didn't seek charges on Cheryl Mills and Huma Abedin for lying. They told Peter Strzok that they had no knowledge of the Queen's secret server despite evidence that they knew all about the Queen's secret server. Must have been due to the immunity deals they had despite being targets of the investigation. I'm sure that's routine and intellectually honest too.
