A former pharmaceuticals chief, who hiked the price of a life-saving medicine by more than five thousand percent, has refused to testify in front of lawmakers.
Martin Shkreli, who used to head up Turing Pharmaceuticals, used a Fifth Amendment right against self-incrimination, as he was questioned by a House of Representatives committee.
“On the advice of counsel, I invoke my Fifth Amendment privilege against incrimination and respectfully decline to answer your question,” said Shkreli.
After brushing off questions, the 32-year-old then tweeted that lawmakers were “imbeciles.”
Shkreli sparked outrage last year when he acquired Turing Pharmaceuticals and raised the price of the drug Daraprim to 750 US dollars (670 euros) a pill.
The medicine, used to treat a parasitic infection, once sold for one dollar (less than one euro) a pill and has been on the market for more than 60 years.
Shkreli also faces separate criminal charges of securities fraud in connection with another drug company he owned.
