Okay, I cannot recommend 5calls.org enough. Enter your address and it will find all your reps (federal and state). AND give you a list of issues to call about AND which reps to call about each of them AND a little script for each, in case it's helpful. They have an app, too.

We want to send a message to the world: what has happened today is an absolute disgrace. It is completely un-American.

These are the good guys supporting DEI. Reward them with your business.
