Big decision to be heard in few days on 12 May by US supreme court. About if President can block subpoena requesting release of his financial details help by accounting firms or banks.
The bigger simple question is really 'is the US president above the law' for the duration they are in office. Trumps lawyers argued in a lower court that 'should the President shoot and murder someone in cold blood on 5th avenue, then no authority should be allowed to investigate him or prosecute him for such murder whilst he held the office of President, only after he no longer held that position'. All precedent on this to date had been that , a serving president is NOT above the law, whilst he is serving. What Trump is seeking from the Supreme court is a ruling that a sitting president IS above the law for as long as he is President. I personally hope the Supreme Court follows all legal precedent and all moral imperative to explicitly state (once again) that NO ONE is above the law, the President included.
