Much-despised drug CEO Martin Shkreli smirked and laughed at members of Congress while refusing to answer their questions Thursday, later calling them “imbeciles.”

Shkreli vented his dislike on Twitter after refusing to testify before a House Committee about his infamous decision to increase the price of a lifesaving drug by 5,000 percent. He invoked his Fifth Amendment right to avoid self-incrimination, and smirked and laughed at representatives who wanted to question him.

“I don’t think I’ve ever seen the committee treated with such contempt,” Representative John Mica, a Florida Republican, said after Shkreli left the room, according to The New York Times.

Separately, Shkreli was arrested on fraud charges related to his time as a hedge fund manager and as head of his former company, Retrophin.
