I am very much in love with Trump fans throwing tamtrum everywhere they go because they lost . I mean you can try to make it look like "media says Biden won, we have to wait for official results by states!!!" all you want, that media you do not believe didn't made the numbers up, they didn't get the numbers from their friends, these are literally the voting totals given to everyone in public (you can go ask and take it yourself as well) by the states and election officials, these are not some vague and "estimated" or "guessed" or polls or anything like that, these are literally the official results by election officials given to public.

Hence the results are as official as it gets, what is left however is finishing it all, doing the paperwork and declaring it which won't be few days, it will definitely take a couple weeks but numbers are not given to you by media, it is just the middle man.
