In an interview with The Washington Post, Nunberg said he was asked to come to Washington to appear before the grand jury on Friday. He also provided The Washington Post a copy of his two-page grand jury subpoena seeking documents related to President Trump and nine other people, including emails, correspondence, invoices, telephone logs, calendars and “records of any kind.”

Nunberg forwarded an email from the office of special counsel Robert S. Mueller III seeking his appearance in front of the panel on Friday…

“Let him arrest me,” Nunberg said. “Mr. Mueller should understand I am not going in on Friday.”

Nunberg said he was planning to go on Bloomberg TV and tear up the subpoena.
