I'd guess that if he was an agent, he isn't acting voluntarily. Instead he's probably influenced by chinese and saudi money.
Another simpler, but just as plausible explanation could be that he's basically a human with a giant ego that bounces from one incident to another. None of this seems very planned. Instead he seems to be acting on a whim.
I guess that could be explained with the giant ego. Due to being so smart, he understands the situation better than the mainstream media. The easiest opposing view to latch onto would then be Russian propaganda.
EDIT: I have several friends who are also smart, and as such must question all msm news. As a result their worldview is left with a void that is usually filled with more fringe opinions.
