right. the narrow version is something like: Roberts held that the direction of the DOJ is a core power, as are communications with executive branch members about official business. Everything else is theoretically in the air.
Of course couldn't you order government officials to do a lot more things now by saying you'll pardon them if they break the law for you, but you'll fire them if they don't? The president for sure can't be prosecuted for using his pardon now, right?
