Special counsel John L. “Jack” Smith has subpoenaed election officials in Allegheny County, as well as others in Wisconsin, Michigan and Arizona, asking for communications with or involving former President Donald Trump, his campaign aides and a list of allies involved in his efforts to try to overturn the results of the 2020 election.

The requests are the first known subpoenas by Smith, who was named special counsel in November by Attorney General Merrick Garland.

Smith, a former career Justice Department prosecutor and former chief prosecutor for the special court in The Hague, has been charged with overseeing the Justice Department’s investigation into the presence of classified documents at Trump’s Florida estate as well as key aspects of a separate probe involving the violent storming of the Capitol on Jan. 6, 2021, and Trump’s efforts to remain in power.

First reported by the Washington Post, the subpoenas seem to indicate that Smith’s work will include an examination of local election officials and their potential interactions with the former president and his representatives.

Allegheny County, the Commonwealth’s second most-populous county and home to the city of Pittsburgh, has confirmed receipt of the subpoena to PoliticsPA.

The requested communications from June 1, 2020 through January 20, 2021, in Wisconsin and Arizona include those with Trump’s campaign manager, Bill Stepien, and other advisers, such as Boris Epshteyn. Attorneys identified include Trump campaign lawyers, such as Justin Clark and Matthew Morgan, as well as those serving in other capacities, such as John Eastman, Rudy Giuliani, Sidney Powell and Cleta Mitchell.

A Justice Department spokesman declined to comment.
