The notorious hedge fund manager-turned price hiking biotech executive was met with protests and general name-calling during the event, which was hosted by the Harvard Financial Analysts Club on Wednesday evening. In fact, the talk started late because somebody pulled the fire alarm and police had to evacuate the building where it was taking place, according to CNBC.

The protesters eventually left, and there were no reports of violence. But there were also counter-events being held by student groups at the same time as Shkreli’s talk, including a “teach-in” about pharma price hikes.

For his part, Shkreli discussed his experience in managing hedge funds and health care specifically. He is currently under indictment for alleged securities fraud and out on $5 million bail. That trial is set to start this summer.

Shkreli, in many ways, helped bring a glaring spotlight to the issue of drug pricing with his 5,000% increase on a cheap drug used by HIV/AIDS and cancer patients. Since the brouhaha broke out, the Pharmaceutical Research and Manufacturers Association (PhRMA) has taken pains to distance itself from Shkreli, who it says doesn’t represent the spirit of innovation which drives biopharma.

But Shkreli’s hit back hard recently. He launched a website tracking pharma company “skeletons” on drug price hikes in an effort to show that many drug makers share his methodology without eliciting the same kind of outrage. He even credited the latest drug price hike villain, Marathon Pharmaceuticals, with “teaching” him how to take advantage of existing regulations to increase prices.

One line from Shkreli’s talk that’s sure to stick out? “[President Donald] Trump should start a drug company. I would be proud to help implement this.”
