"Pharma Bro" does video chat with public following congressional hearing

In a video live chat Thursday, Martin Shkreli took questions from the general public following a congressional hearing in Washington, D.C. where he stonewalled Congress. And Congress wasn't the only one Shkreli stonewalled. When CBS News' Valdimir Duthiers joined the online video chat, Shkreli immediately shut him down. CBSN has more.
