Martin Shkreli, the former CEO of Turing Pharmaceuticals, infuriated members of the congress after he repeatedly dodged their questions relating to his increase of drug prices.

The 32-year old "pharma bro" has got himself into a series of controversies, starting when he jacked up the price of Daraprim, an anti-viral drug. He got further buried on the controversy when he appeared on multiple interviews and showed no remorse whatsoever regarding his acts.

During his summoning at Capitol Hill, members of the congress asked him repeatedly regarding Daraprim, but continued to utter the phrase, "On the advice of counsel, I invoke my Fifth Amendment privilege against self-incrimination and respectfully decline to answer your question."

Throughout the whole hearing, Shkreli kept a smirk that obviously irritated members of the congress. Trey Gowdy, a representative from South Carolina even asked him about his purchased Wu Tang Clan album, in which Shkreli again insisted on his Fifth Amendment rights, The Seattle Times reported.

Maryland Rep. Elijah Cummings also took his turn on addressing Shkreli and decided to employ a different tactic on interacting with him. Instead of using the usual angry and vilifying tone, Cummings opted to appeal on his humanity and practically begged him to lower drug prices.

But to no avail, Shkreli smirked and did not offer a response. Cummings said, "I know you're smiling, but I'm very serious, sir," he added, "You could go down in history as the poster boy for greedy pharmaceutical executives, or you could change the system. ... I truly believe you can be a tremendous force for good," CNBC reported.

After failing to answer even a single question, Shkreli was dismissed less than an hour later. With his exit, Florida Rep. John Mica expressed his disdain with the former pharmaceutical CEO and said that he has never witnessed the congress to be treated with such contempt and disrespect.

Bejnamin Brafman, Shkreli's lawyer, defended his client and said that he never intended to be disrespectful and attributed Shkreli's smirks and fidgeting as "nervous energy."

Further angering the congress, Shkreli tweeted moments after the hearing that he finds it hard to accept that "these imbeciles" represent the people in the government.

Brafman expressed regret over his client's tweet and just attributed it to Shkreli's youth and inexperience. He said, "He's never been in this position before and it's a regrettable choice of words."

Shkreli is currently facing criminal charges of securities fraud in connection to another drug company that he owned.
