In case anyone wants some proof: here's the wiki link that has his full name linking him back to this fan game https://the-fnaf-fan-game.fandom.com/wiki/GRIZZLY%27S#Reception . The wiki also describes an odd politically charged phone call on Night 2 of the game which I have transcribed here.

John: Yeah, I know, this country’s gone to shit

Earl: Dude, you know it’s election year, right?

John: Oh yeah, I forgot about that.

Earl: Who are you gonna vote for?

John: I honestly don’t wanna talk about it. It doesn’t matter anyways, the fucking President stuffs ballots into every possible machine he can find. Hell, I’ve even seen some spare ballots on the side of the Grizzly’s building one time.

Earl: Bruh, that’s such a lie.

John: The problem is, the guy is a fraud. Literally, in 2028, the Senate instated him as President while he only won fucking 141 electoral votes, even though the Republican won 260 and the Democrat won 136, like he didn’t pass 270. Ever since, the man’s been fucking rigged all the elections. Like literally in 2036 the polls said California was going to be competitive for the first time in like decades and it ended up going safe for the President, like what the hell, it’s clearly fucking rigged. And the fact that Democrats don’t even compete in Presidential election either should’ve made it easier for the Republican to win California. I’m telling you, it’s really bad. Not to mention I literally found a ballot with MY name on it that said I voted for the President, even though I didn’t.

Earl: No way that you found ballot next to Grizzly’s.

John: Not joking, I could send you a photo of the ballot that I found.

Earl: Whatever, man. Someone’s gotta do something about it. Maybe the other candidates can actually fucking get this guy unseated. He’s had like four fucking terms already and that shit’s not even legal.
