He said the pricing situation was "blown out of proportion," and he mentioned Valeant and Pfizer, the world's second-largest-drugmaker, as other companies who have raised prices recently. Turing did not respond to requests for comment.
He also said he's made many fans in the business world. "Everybody's doing it. In capitalism you try to get the highest price you can for a product," he said.
He was at turns thoughtful and sarcastic during the interview, asking Bloomberg anchors David Westin and Jonathan Ferro, "I don't know if you're familiar with health-care insurance," and saying patients don't feel the brunt of price increases. While drugs make up about 10 per cent of overall health-care spending in the US, insurers often implement cost-sharing with patients and increase the premiums patients pay in response to long-term rising costs.
Federal prosecutors have accused Shkreli of defrauding investors in the hedge funds, and of using $11 million (NZ$16m) of Retrophin assets to pay them off. He also allegedly hid his control in the company's unrestricted stock to help pay off his debts. He was arrested in December 2015 and has pleaded not guilty.
He said he's looking forward to the upcoming trial, scheduled for June.
"We're going to win by a landslide," he said. "The evidence is clear that I did nothing wrong."
Shkreli is known for his blunt opinions in an industry that often tries to present a unified front. During a congressional hearing on drug prices in February, he invoked his Fifth Amendment rights as a way of refusing to answer questions, then after the hearing called lawmakers "imbeciles" on Twitter.
During his trial, Shkreli predicted that jurors will see somebody they can relate to, not the figure he claims he's been portrayed as in interviews. "Invariably, when people read the headline about Martin Shkreli, they hate Martin Shkreli. When they get to know Martin Shkreli, they love Martin Shkreli," he said.
During the TV interview, Shkreli brought up the US$1 billion federal fraud case against the co-founder and several associates of hedge fund Platinum Partners. The U.S. has accused Platinum of a Ponzi-like scheme. Platinum co-founder Mark Nordlicht pleaded not guilty this week.
Shkreli said he had 'tangoed" with the hedge fund over a trade, before investigators brought the case, and called the investigations and charges an example of what the government should go after. After his interview on Bloomberg, he declined to comment on whether he had spoken to federal investigators about the Platinum case.
