Embattled drug entrepreneur Martin Shkreli — who vigorously defended his decision to hike the price of a life-saving drug from $13.50 to $750 — suddenly went silent Thursday at a Congressional committee, smirking and grinning instead of answering questions.
Now facing an unrelated federal criminal indictment, the typically loquacious Shkreli refused to testify, repeatedly citing his Fifth Amendment right not to incriminate himself.
Members of Congress launched into fiery lectures directed at Shkreli, whose previous company, Turing Pharmaceuticals, came under scrutiny when it raised the price of Daraprim more than 5,000%. The pill is used to treat toxoplasmosis, a parasitic disease that afflicts people with weakened immune systems, such as those with AIDS and pregnant women.
After the hearing, he removed any doubt about his feelings.
"Hard to accept that these imbeciles represent the people in our government," Shkreli said on Twitter.
