The just-starting Senate impeachment trial of President Trump has resurfaced reminders of what isn't allowed in the room where it happens: talking, electronics, questions from the press, among other things.

Rick Scott (R-Fla.) has just generously reminded us that another liquid will be available for slurping come trial time.

Yes, because one senator desperately needed a dose of dairy back in 1966, milk is allowed on the floor along with water. No senators have broken out the dairy this impeachment around, but keep an eye on Vermont Sens. Bernie Sanders (I) and Patrick Leahy (D), who've been spotted sipping milk together on special occasions for decades. Kathryn Krawczyk
