Obvious statement but a potential law breach is becoming political. If he had fiddled his taxes (he's a business owner, you work out of he has), then its a criminal matter. Seems there is a specific agenda because hes the president, very high profile and its election year. However hes the biggest available fish (bigger fish are in the ocean) and one that is easily hooked (look at his Twitter). In my opinion hes not fit to be in the position of president. Its a way too powerful position for a nutter and egomaniac like him but I also have severe doubts over opposition Joe Biden and Hillary Clinton (both on dodgy territory). Alas I'm not American, so my opinion probably goes as far as AVFTT (if anyone is interested).
