U.S. Supreme Court Justice Elena Kagan and dozens of lawyers who argue at the U.S. Supreme Court turned out Thursday to celebrate the career of newly retired deputy U.S. Solicitor General Michael Dreeben, who argued more than 100 cases before the court and aided special counsel Robert Mueller III in his Trump investigation.

Known as a straightforward, no-nonsense expert on federal criminal law, Dreeben displayed his lighter side at the party, which took place at a downtown Washington bar called Dirty Habit, a name that is difficult to imagine being associated with Dreeben.
