We understand witnesses and Senator doing the questioning. It is the absence of manners and respect in these hearings. She has been a regular offender in attacking witnesses as though they were criminals and not Senior Executives, Cabinet picks, and even the A>G and Director of the FBI. Harris is just trying to make a name for herself. Male Senators who routinely act this way are also jerks if they believe this is appropriate. All it brings is the witnesses that follow taking the 5th, not appearing, or being hostile.
