Well, yes. But not here. I don't think he'd go in and troll the real Elizabeth Holmes when he has the chance to do real journalism.
Admittedly seeing him at first made me think "wow that lady sounds exactly like Holmes". Then I realized it was supposed to be her and thought "wow, they did an amazing job casting her".
Then I realized it was her, at which point it was immediately clear this was a serious endeavor and not something Fielder typically does.
