Wish it had email addresses.
Google anyone of their names and you’ll get their offices in DC. I’ve done with it a few of them. You’ll get a phone number of their office and a recorded message of how wonderful they are and how happy they are that you’ve called their wonderful selves and please leave your message after the beep.
I’ve called a few of them. Left my name and phone number and messages that would make the US Marine Corps blush.
I’ve never threatened. Don’t do that unless you want the FBI or the Secret Service to pay you a call but by all means means never be afraid to let them know how truly worthless their wonderful selves are.
