Gee, honestly - his friend isn't helping LOL. "Nothing more to see..." is how that is going to be read by the "other" side. And let's be honest - if anyone did this, people would be suspicious. I personally doubt there is anything there (or it would have come up previously), but that doesn't change the optics and either "side" would use that to their advantage. Just the very fact of we wouldn't even be talking about him and his tweets if he hadn't deleted them.
What I am most confused about is that I don't know how suddenly we have forgotten in 2018 what we knew in 2008, and frankly, by 1998, - that you can't "delete" stuff from the Internet. Especially when you have nearly a million followers, many of whom get notifications, updates on their mobile devices, etc., every time you click "send".
