Former Vice President Mike Pence has been subpoenaed by the special counsel overseeing investigations into efforts by former President Donald Trump and his allies to overturn the results of the 2020 election. That’s according to a person with direct knowledge of the subpoena who spoke to The Associated Press on condition of anonymity Thursday to discuss a sensitive issue. The subpoena to Pence as part of the investigation by special counsel Jack Smith was served in recent days. The extraordinary scenario of a former vice president potentially testifying against his former boss in a criminal investigation comes as Pence considers launching a 2024 Republican presidential bid against Trump.
