Here's a copy and paste of the spoliation letter template from George Webb's YT channel. I'm assuming that this is the template that each constituent is using to send to the representative of his or her respective district.

"Dear Congressman:

It has come to my attention through an investigative reporter named George Webb that a spy ring may have operated in Congress since January of 2000. I am deeply troubled by this news. I have read articles from the Daily Caller by Luke Rosiak and Heather Cagill of Politico that there have been twenty Congressional burglaries, and key IT equipment like hard drives and laptops may have been stolen. Sean Boburg of the Washington Post also writes the House Inspector General has a report outlining 5,100 illegal logins over a period of seven months from March 2016 to October 2016 to a House Caucus server. This is especially troubling to me since this was during the period of a key campaign between Bernie Sanders and Hillary Clinton.

When these revelations are included with the DNC and Podesta wikileaks scandals, it paints a troubling picture, considering that the ringleader of this alleged spy ring, Imran Awan, worked directly for Debbie Wasserman Schultz, the head of the DNC. I also understand a physical confiscation of hard drives and a laptop was made on April 6th, 2017 at the Rayburn Office Building next to the Capitol from the person of Imran Awan after he was banned from access to the Congressional network on February 2nd, 2017. I understand there is a chance by private conversations and concerns that I have shared in confidence with the Congressman are contained in a system called iConstituent, and this systems records may have been breached. I am hereby requesting screenshots on my account records in iConstituent in preparation for a potential lawsuit against the Awan spy ring.

This is your notice, under the Federal Rules of Civil Procedure, to safely protect and archive all electronic messages, text messages, electronic files, and other evidence that has been transmitted, stored or processed by any information technology (I.T.) system in your possession. This would include all such I.T. systems, no matter in your personal use, Capitol office or district offices. As you know, this includes all media such as USB sticks, DVD/CD media, hard drives, etc. Any destruction of evidence will be viewed by the federal courts as an abuse of this notice and can be construed as a criminal act or be liable for criminal sanctions. You now have a duty to safely archive, store and protect all such evidence between 2000 to 2017. Your office and staff should seek legal counsel to implement this litigation hold demand (spoliation notice).

Thank you,

Your Constituent,"

edited to clean up my typos, but the text in between the quotes was unchanged.
