"I know that he has previously spoken with some of you, if not all of you, and one of the conditions of my engagement was from henceforth he does not speak with any member of the press at all until the criminal charges are resolved," Benjamin Brafman, Shkreli's new attorney, told reporters Wednesday outside U.S. Federal Court in Brooklyn, where Shkreli was appearing for a hearing related to securities fraud charges.
Brafman added, "We believe this case is very defensible. We don't believe that Mr. Shkreli ever knowingly violated the law or intended to defraud anyone, and we want to try this case in the courtroom and not in the media."
Shkreli has spoken to a number of reporters after he was indicted in mid-December, and also is in the habit of live-streaming his daily routine on the Internet to viewers.
Despite Brafman's vow of silence for his client, a wide-ranging interview that Shkreli gave"The Breakfast Club" show on Power 105.1, a New York City hip-hop station, was posted Wednesday morning, before he showed up in court.
Brafman told CNBC that the interview was recorded Tuesday, "before we came to an understanding" about Shkreli needing to put an end to his contacts with the media.
"I'm confident I'll beat the charges," Shkreli said during the interview, in which he described growing up under modest circumstances with parents who worked as janitors. "I'm from the streets," said Shkreli, who also defended making a video last week insulting renowned rapper Ghostface Killah.
"He disrespected me," Shkreli said of Ghostface Killah, a member of the Wu-Tang Clan, whose one-of-a-kind album Shkreli purchased last year for $2 million.
"If he were here right now, I'd smack him right in the face," Shrekli said. "Come at me, it don't matter."
And after appearing in court Wednesday, Shkreli re-tweeted Twitter postings about his Power 105.1 interview.
Shkreli, who recently fired his previous legal team, arrived at the courthouse in a blue blazer and bright white pants. Looking relaxed, the 32-year-old Shkreli smiled and laughed at times before the the start of the hearing, which lasted just under 15 minutes.
During the session, it was disclosed that Shkreli's E-Trade account — which had about $45 million in it when it was used to secure his $5 million criminal release bond — is now valued at just around $4 million.
The decline in the value is due to the account's large holdings of KaloBios stock, which had spiked to almost $40 a share in late November after an investor group led by Shkreli purchased a controlling interest of 1.2 million shares and the company named him CEO.
Assistant U.S. Attorney Winston Paes, who is prosecuting Shkreli, noted the stock plunge since Shkreli's indictment had devalued the bond's collateral. Paes pointed out that KaloBios shares were trading at just over $2 per share on Tuesday.
