Everyone's least favorite pharma bro is at it again this week as he publicly and loudly ignored a congressional subpoena demanding he travel to DC to testify in front of lawmakers. Martin Shkreli, who made news for both drastically increasing the price of life-saving drugs and purchasing the one of a kind Wu-Tang album, was arrested on charges of securities fraud last December with the terms of his bail dictating that he remain in New York state. It is his failure to seek court approval to travel to DC that has angered at least one lawmaker.

“Mr. Shkreli was subpoenaed to appear before Congress, and it is his responsibility to take reasonable steps to comply," Maryland Congressman Elijah E. Cummings said in a statement yesterday. "If he plans on trying to use his own intentional inaction as some kind of bogus excuse for not showing up at Tuesday’s hearing, people will see right through such a juvenile tactic."

Cummings is the ranking member on the House Committee on Oversight and Government Reform, and the representative seeks to have Shkreli testify regarding his August 2015 overnight price hike of the drug Daraprim from $13.50 a tablet to $750.

Shkreli responded in what seems to be the only way he knows how — by mocking the federal government on Twitter.

The aspiring rapper goes on to argue that as he is charged with securities fraud, his 5th amendment protection allows him to skip the committee hearing. Thus Shkreli has made no legal arrangements to get to DC.

"Your attempt to subvert my constitutional right to the 5th amendment are disgusting & insulting to all Americans," he tweeted yesterday to both Representative Cummings and the Oversight Committee.

As the fraud case against Shkreli is unrelated to the price hike he orchestrated as CEO of Turing Pharmaceuticals, and rather focuses on his alleged "Ponzi scheme," it is unclear if the argument will hold water.

Cummings doesn't appear to be messing around, however, and the statement issued by his office drives that point home.

"Several federal statutes could be implicated if Shkreli does not comply with the subpoena," it notes. "The Committee could seek to hold him in contempt under 2 U.S.C. Section 194, and he could receive jail time and financial penalties under 2 U.S.C. Section 192."

We won't have to wait very long to see how this very entertaining drama plays out — Shrekli has only a few days to decide whether or not he will comply as the subpoena requests he appears in front of congress on January 26. But who knows, he might just cross his fingers and hope for a snow day.
