She DID inform the Senate. She informed all Americans. Senators are Americans. When impeachment laws and rules were established, there wasn’t 24/7 media, and instant information.
Mitch can begin the trial. She can make a presentation for impeachment or not. Her choice. Maybe she’ll decide to take her dollies and go home and pout.
