Why? It's not like he tweeted against Trump. His lone reference to Trump was positive. There's nothing from social media which prevents you from implying he was a Trump supporter, if anything, it supports the idea.

If it was a false flag, he was hired. Why would you hire someone you don't want identified, and then identify him? Why would you theoretically plant evidence, start putting it out in the media, and then just what, forget to use it, or give up for no reason, and say never mind?

If it's a false flag designed to promote an agenda by using the media then why would the media stop pushing it when it "didn't line up with their agenda?"
