Yesterday, Ars reported on the Reddit thread purported to have been started by Paul Combetta, a systems administrator at Platte River Networks involved in the operation of Hillary Clinton’s private mail server. In the thread, a user named “stonetear” asked others on the /r/Exchangeserver subreddit how to strip a “very VIP” person’s e-mail address from messages in an existing Exchange .PST e-mail archive.

Now, the House Oversight and Government Reform Committee, which has been at the center of much of the ongoing congressional probe into Clinton’s e-mails, has subpoenaed those posts. The feds are asking Reddit to preserve them for further investigation. The Hill reports that the committee’s Republican majority has issued an order to Reddit to provide the posts and metadata related to them to committee investigators, and Reddit is reportedly cooperating with the order.

The Justice Department previously granted Combetta immunity from prosecution for cooperating with the FBI’s investigation of the Clinton e-mails. Combetta admitted to accidentally deleting Clinton’s e-mail archives in an “oh shit moment” when he realized he had not put new retention policies in place for her mail.
