everyone should be considered innocent until proven guilty.

Yes, absolutely. But the thing is that a lot of things are proven during trials that are immoral but not illegal. He could still have done a ton of indefensible stuff that makes him a bad person but still get a not guilty verdict. My point is that "Not being a criminal" is the lowest tier we should judge a person. If we are going to give a person a large amount of money and influence we are allowed to ask for more.
