Former Trump White House counsel Pat Cipollone subpoenaed by Jan. 6 panel

Donald Trump's former White House counsel Pat Cipollone has been subpoenaed for a deposition by the House's Jan. 6 committee.

"The Select Committee's investigation has revealed evidence that Mr. Cipollone repeatedly raised legal and other concerns about President Trump's activities on January 6th and in the days that preceded," the committee's chair and vice-chair, Mississippi Democrat Bennie Thompson and Wyoming Republican Liz Cheney, said in a statement on Wednesday -- one day after Cipollone was repeatedly mentioned during the testimony of Cassidy Hutchinson, who was a top aide to Trump's chief of staff Mark Meadows before and during the Jan. 6, 2021, attack on the Capitol.

A lawyer familiar with Cipollone's deliberations told ABC News in response: "Of course a subpoena was necessary before the former White House counsel could even consider transcribed testimony before the committee."

This source noted that Cipollone "previously provided an informal interview at the committee's request. Now that a subpoena has been issued, it'll be evaluated as to matters of privilege that might be appropriate."
