Yeah, that's new but according to The Norweigan Nobel Committee, the Norweigan Nobel Institute, the Peace Research Institute, and the Chief Inspector for Oslo economic crimes division, every previous nomination for him was forged by someone using a stolen identity.
It wasnt until someone convinced a random Norweigan politician to nominate him that his nomination was considered legit. Interestingly, that politician is a 'Norway first' anti immigration guy and does not believe in climate change. He's also criticized western nations for "too strongly" condemning some of russia's actions in the past. he also thinks that Norway's conservative party is not conservative enough. He once claimed he got physically sick because of the hostility toward him in the media.
So it makes sense that this guy would be trump's nominee.
