This IMO smacks of damage control. The public is already aware of the current administrations attempts to harass right wing activists, spy on the press, sleep on the enemy, violate the constitution, etc.
By Mueller claiming ignorance he can't make things any worse than they already are.
The liberals are HOPING this will eventually die down and disappear into anonymity.
I hope quite the opposite. There is clearly no excuse for this behavior. People need to be held accountable for their actions.
I would never condone this from a republican admin. and you would think the Obama admin. has a little more pride than allowing sh*t like this to go on.
