That's an overly charitable interpretation of what he's doing.
The pattern that I've observed is: 1) he's a narcissist who always wants to be in the news and/or 2) he's trying to distract from something.
He can't stand it when the press moves on from him. His MO is to wait for a week or two and then throw out something outlandish to suck up the media oxygen.
He and Trump are very similar people.
