NYT:

Former Vice President Mike Pence has been subpoenaed by the special counsel investigating former President Donald J. Trump’s efforts to cling to his office after he lost his bid for re-election, a person familiar with the matter said on Thursday.

The move by the Justice Department sets up a likely clash over executive privilege, which Mr. Trump has previously used to try to slow, delay and block testimony from former administration officials in various investigations into his conduct.

The existence of the subpoena was reported earlier by ABC News.

It was not immediately clear when the special counsel, Jack Smith, sought Mr. Pence’s testimony. The move is among the most aggressive yet by Mr. Smith in his wide-ranging investigation into Mr. Trump’s role in seeking to overturn the outcome of the 2020 election and a parallel inquiry into Mr. Trump’s handling of classified documents.
