Jurors have deliberated for a second day at the federal securities fraud trial of former pharmaceutical company CEO Martin Shkreli.

They got the case Monday in New York and spent a full day deliberating Tuesday before ending the day without a verdict. Deliberations resume Wednesday.

Prosecutors say Shkreli looted his drug company to pay back investors in two failed hedge funds he ran. The defense says investors got their original investments back and even made hefty profits.

The former biotech CEO - nicknamed "Pharma Bro" - is best known for hiking up the price of a life-saving drug and for trolling his critics on social media.

If convicted of the most serious counts, he could face up to 20 years in prison but likely would receive far less time under sentencing guidelines.
