Former Vice President Mike Pence is expected to fight a subpoena issued by Special Counsel Jack Smith, who is investigating former President Donald Trump's post-2020 election activities. Pence will argue that he is protected by the Constitution's Speech and Debate Clause due to his role as president of the Senate. He is expected to announce his decision to fight the subpoena during a pre-campaign stop in Iowa on Wednesday. The legal battle is likely to be a long one, as Smith's office is expected to challenge Pence's argument.
