The findings thus far have been anything but legitimate
Well since nothing regarding charges have been leveled so far at the President, it would be next to impossible to say the findings against him have been anything but legitimate. There have been some convictions of others in the orbit of this investigation as well as some guilty pleas while avoiding trials. Mueller may come back with nothing. Or he may have charges to level. White collar crimes often take time. Much more time to piece together than your common thug crimes. And prosecutors/investigators even after a lengthy period may come back empty handed.
My guess is any legitimate charge would be classified as anything but legitimate among many Trump supporters. As he said, he could kill someone on 5th Ave and get away with it.
