https://www.nytimes.com/2019/05/20/us/politics/mcgahn-trump-congress.html Obstruction/Intimidation. This puts McGahn in a pretty tight spot. The committee’s chairman, Representative Jerrold Nadler of New York, said last week that he was prepared to have his panel vote to hold Mr. McGahn in contempt of Congress if he does not show up on Tuesday. Though a black mark on a witness’s record, a contempt citation would most likely result in the House turning to a federal court to try to enforce its subpoena. At the same time, if he defies the White House, Mr. McGahn could not only damage his own career in Republican politics but also put his law firm, Jones Day, at risk of having the president urge his allies to withhold their business. The firm’s Washington practice is closely affiliated with the party.
