After that they will then be stored forever! By the way, “deleted tweets” will not be part of the archive; however, if you delete a tweet AFTER it has already been archived by the Library of Congress, that tweet will STILL remain archived. Even though it is deleted from Twitter, it will still show up, in perpetuity in the Library of Congress.
