Thatnks for your comment and for letting me know there's one more political hack out there.
Since the form to use is on the Justice Department website, somebody there will get what you send. If enough people send the same message, I do think the message will get to Merrick Garland. This won't happen if I complete the form, or if you do, but it may happen if a thousand political hacks send the message. Since he's also being pressured to do something by every newscaster I watch, and presumably by every Democrat in the House, he may act. Anyway, do you have a better suggestion?
