On Wednesday evening the House Select Committee investigating the Trump coup plot issued a subpoena to former White House counsel Pat Cipollone, following blockbuster testimony from former White House aide Cassidy Hutchinson, who said the lawyer had warned of potential criminal activity by former President Donald Trump and his aides.

The committee summons to Cipollone followed long negotiations over his possible appearance and increasing pressure on him to come forward as Hutchinson did. Committee members expect the former counsel’s testimony to advance their investigation, owing to his knowledge of the former president's actions before, during and after the January 6, 2021 attack on the U.S. Capitol.

Cipollone sat for an informal interview with the committee on April 13, according to a letter from the panel’s chairman, Rep. Bennie G. Thompson (D-MI), but has since refused to cooperate. He is likely to fight the subpoena in court.
