The party of 1984. They couldn’t possibly adhere to it any closer.

In this way every prediction made by the Party could be shown by documentary evidence to have been correct, nor was any item of news, or any expression of opinion, which conflicted with the needs of the moment, ever allowed to remain on record. All history was a palimpsest, scraped clean and reinscribed exactly as often as was necessary.

Orwell, 1984

They just make shit up like what actually happened or what they said before never existed.
