NJ flew the flag half mast because she was born and raised in Newark. That makes a bit more sense than NY flying the flag at half mast. At least only fly the state flag at half mast if you are going to do something like that, and not the US flag.
I agree. I would have no issue with the State flag if they decide to do so but I don't think some Governors should have the right to do so for the US Flag. That should strictly be a federal decision.
