I know it's something of a fool's errand, but I really don't understand Trump's logic here.
"it was an illegal investigation that should never have been allowed to start."
Wasn't it started by Rod Rosenstein, using the accepted process for appointing a Speical Counsel? What is illegal about it? I understand that he doesn't like it, and thinks it was a witch hunt, hugely influenced by Democrats (depsite being authorised and overseen almost entirely by Republicans) etc. etc. - but in what way was it illegal?
