'Unbalanced' is the term of art used by Nooz types to describe a nutbag.
Daily Mail comes extremely close to saying the quiet part out loud:
Nancy Pelosi crashed the House impeachment manager's post-trial press conference Saturday to rage against Mitch McConnell and call out Republicans' 'cowardly' vote to stop Donald Trump from being convicted for 'incitement of insurrection'.
It is VERY rare for any figure--no matter who--to "crash" a presser in D.C.
She's Biden-izing her sentences and lost control of herself:
... 'What is so important about any one of us, what is so important about the political survival about any one of us that is more important than our Constitution that we take an oath to protect and defend?' she questioned, shaking at times with anger....
CLEARLY lost control of herself:
...Pelosi, who tried to leave the room two separate times but walked back to the podium to add more, was livid....
McConnell--quoted in the article--is also unhinged regarding Trump. Might be fun to sneak up on Cocaine Mitch and yell "TRUMP!! TRUMP!!!" to see if he goes into a catatonic state.
