You're trying to imply there's some contradiction between the three statements, but there really isn't. For one, X never claimed "they've not been made aware of the allegations". The exact wording used in the article was "it “remains in the dark” about the specific allegations", which is different than not being aware of the allegations at all. Moreover it's not contradictory to deny allegations that you're not aware of the specifics about. For instance, if someone accused you of saying a racist thing, but didn't reference a specific incident, it'd be pretty reasonable to both claim you're "in the dark about the specific allegations", and to deny it. It'd also be reasonable to claim it's politically motivated, if for instance it was coming from someone you had beef with.
