An Answermug pal brought up a topic I have never thought about. "Booze" in a judge's chambers and in Congress. Alcohol consumed at work?

I think it is not a good thing to have booze at work and imbibe during working hours. But what's to stop Congressmen or Senators or Judges from keeping bottles of the stuff in their offices and taking a drink whenever they wish? Which makes me wonder how many pols are sober during  their day at work and how many are potted like plants and their colleagues just live with it?
