The committee’s subpoenas had set a Thursday deadline for Bannon, Meadows, Patel and a fourth witness, former White House communications aide Dan Scavino, to provide documents. They also set dates for interviews next week. Patel said in a statement that “I can confirm that I have responded to the subpoena in a timely manner” but would not elaborate. A spokesman for the committee declined to comment on whether Scavino was cooperating.
