Under what law, I would like to know (as always)?
The constitution explicitly says POTUS needs permission from both chambers to address congress in the capital building (or words to that effect).
Is it petty and stupid? Yes. Is it well within her legal right to do it? Yes.
I FOR ONE WOULD LOVE TO SEE ONE DAY PASS WITHOUT SEEING OR HEARING THE WORDS "TRUMP" OR "PELOSI".
McCain who ?
August 25th - a bright spot in 2018.
