Here's the now-unsealed order holding Roger Stone associate Andrew Miller in contempt after he refused to testify before special counsel Robert Mueller's grand jury. 
Miller has appealed the contempt finding to the D.C. Cir., and its enforcement is stayed pending that appeal. His opening brief is due today.
(Stayed pending appeal means he's not in jail. This - being held in contempt - is how you raise a subpoena issue for appellate review.)
