Why did Trump cancel his press conference where he had "detailed, irrefutable" evidence and "conclusive, complete exoneration" ?

Maybe he decided to put his election lies behind him and run on a platform of things that will benefit all Americans - yeah right then a gorilla flew out his butt. (usually it is a monkey that flies out of peoples butts but Trump's butt is so big there would be plenty of room for a gorilla) Cheers and happy weekend!
