Hoffman v. United States

Hoffman was subpoenaed before a grand jury investigating racketeering and refused to answer questions about his occupation and about his contacts with an associate, Weisberg, who had also been subpoenaed but failed to appear; Hoffman invoked his privilege against self-incrimination. The district court found no real danger of self-incrimination and ordered him to answer, and when he still refused, he was convicted of criminal contempt, which the court of appeals affirmed.
