Seance Begins at Nine Tonight

"He shall from time to time give to the Congress Information of the State of the Union, and recommend to their Consideration such Measures as he shall judge necessary and expedient; he may, on extraordinary Occasions, convene both Houses, or either of them, and in Case of Disagreement between them, with Respect to the Time of Adjournment, he may adjourn them to such Time as he shall think proper; he shall receive Ambassadors and other public Ministers; he shall take Care that the Laws be faithfully executed, and shall Commission all the Officers of the United States."

The most presidential and least orange Trump I could find

There you have it. That's the history behind the reason for the annual appearance of the President of the United States speaking to the assembled Congress. I've never understood where the 'equal time' provision for the loyal opposition on all the broadcast TV networks comes from, but that's a quest and query for another time. 

As you've already surmised, I don't especially care what Cadet Bone Spurs says (but others do and these folks will track his every word); what he and his crony kleptocrats have done is more than enough to turn my stomach though he seems to have no track record of honesty or veracity to fall back on. 

Sometimes the things we do speak so loudly I cannot hear what we are saying. And perhaps only in my recent memory, that's just as well as shame and anger are about the only visceral responses I seem to have.
