Martin Shkreli — the so-called “Pharma bro” awaiting a verdict in a criminal fraud trial — has taken to social media once again.

NEW YORK — What do you do if you’re one of the most criticized defendants in the nation awaiting a jury verdict on the criminal fraud and conspiracy charges filed against you?

If you’re “Pharma Bro” Martin Shkreli, the often-reviled poster boy for prescription drug price hikes, you turn to social media, of course.

Friday morning, Shkreli mocked a Twitter user who tweeted Twitter founder Jack Dorsey the electronic link to a USA TODAY news story about Shkreli’s semi-surreptitious return to one of his favored social media platforms.

He made the vow after demonstration of how oddly small the world sometimes seem.

The courtroom was cleared for arraignments in a criminal drug and weapons case that featured a different Martin Shkreli — a Bedford, N.Y. man more than 20 years older than the 34-year-old Pharma Bro — as one of the defendants.

The Pharma Bro’s father, Pashko Shkreli, shook hands with the older Martin Shkreli, who, after the arraignment, found himself surrounded by news reporters covering the younger Martin Shkreli’s trial.
