U.S. Presidents have been speaking out to members of Congress for a long time, and vice versa. Supreme Court Justices speak out every week, at the very least, and members of Congress get to have their say every minute of every day, or so it seems.
So, why the fuss when they disagree (e.g. making faces or outbursts)? It’s often about manners (e.g.), or history, or protocol, or even just frustration. Sometimes it’s about maturity and gravitas and mental health and sometimes it’s just about childish behavior. It might help if we had a Question Time where members of Congress could get it all out their systems, but that’s their own fault. If members of Congress wanted a Question Time, they could make that happen (House and Senate).
But we can all speak out. Isn’t that what America is about?
