They've certainly acted guilty and if they're not, I think the Administration has certainly mismanaged this from the git-go: members of the Administration raised doubts about their forthcomings when they “forgot†about meetings with Russians (e.g., Sessions), repeatedly amended security clearance forms with meetings with Russians (e.g., Kushner), misled the American public about meetings with Russians to get “dirt†on Hillary Clinton (e.g., Don Jr., et al), and changed their rationale for firing the FBI Director (e.g., Trump).
I’m not saying any of these things are, in and of themselves, criminal, but if you're not guilty, I think you do yourself a disservice by not doing your homework, not being prepared for testimony/paperwork under threat of perjury, and trying to misled the American people about your actions. I truly believe that had the Administration been forthcoming, honest, and prepared, this whole thing could have been over months ago. Instead, they’ve been repeatedly unprepared, deceptive, misleading, and inconsistent. Yet another self-inflicted wound IMO.
