He absolutely should tweet during the hearing! But only pictures of his grandkids and various golf courses.
Drive. Them. Nuts.
Those kinds of tweets would be fine.
And would be a great troll.
But he absolutely should not tweet anything about Comey without vetting it.
He is not a lawyer.
He is very likely still not familiar with all the legal ramifications of govt....Heck..alot of lawyers arent even familiar with all the ramifications.
All lawyers should be telling him those tweets need to be vetted. Any lawyer telling him it is fine to be tweeting willy nilly about every kind of topic out there should be fired.
