The Bad Boy of Pharmaceuticals Hits Back

Rather than cower as he takes a beating, Mr. Shkreli seems to relish his time in the ring. He taunts his critics on Twitter or wherever he can. (Mr. Shkreli on Bernie Sanders to Fox Business Network: “I don’t think he understands pharmaceuticals at all.”) Most recently, he live-streamed hours of himself at his desk, talking to co-workers and viewers about medical research and investments and tapping at his computer (action high point: hair-twirling). Last month, he and a group of investors took a large stake in another drug company. He sparred contemptuously with an executive of Express Scripts at a recent Forbes conference. And he still has time to occasionally post pictures of cats rolling in cash on Twitter.
