The subpoenas sought information about communications with a range of people, many of them lawyers who were also listed on earlier subpoenas that focused on the fake elector plan. Among the lawyers appearing as subjects of interest on both sets of subpoenas were Jenna Ellis, who was part of Mr. Trump’s initial legal team after the election, and Kenneth Chesebro, a Wisconsin-based lawyer who helped devise the fake elector scheme.
But at least one of the most recent subpoenas included a new name: Bruce Marks, a lawyer in Pennsylvania who had worked on efforts to challenge the results of the election there. In an email, Mr. Marks said, “It is a frightening attack on attorney-client privilege if D.O.J. is targeting my communications.” He said that to his knowledge he had not communicated with any White House employees, though he had been in touch with Rudolph W. Giuliani and Boris Epshteyn, who were acting as lawyers for the Trump campaign and Mr. Trump.
Despite such crossovers, it remained unclear how the examination of Save America PAC intersects with the investigation of the fake electors. The electors strand of the inquiry is being led by a federal prosecutor named Thomas P. Windom. But at least one of the new subpoenas bore the name of a different federal prosecutor in Washington who specializes in fraud cases, suggesting that this avenue of inquiry is devoted primarily to examining the spending and fund-raising at Mr. Trump’s PAC.
The PAC has paid more than $3.1 million to an array of law firms for “legal consulting.” And it has paid salaries to a number of aides to Mr. Trump, including at least four of the new subpoena recipients: Mr. Dollman, Mr. Russell, Mr. Luna and Mr. Harrison. It has also paid the lawyers Christina Bobb and Lindsey Halligan, who have been representing Mr. Trump in the classified documents investigation.
It has also paid several Trump aides who were subpoenaed to testify before the House Jan. 6 committee — the former White House aide Stephen Miller and Taylor Budowich, Mr. Trump’s current spokesman, both of whom appeared before the committee; and Dan Scavino, a former White House aide who refused to comply with a subpoena.
The group donated more than $4.2 million to a pair of groups that unsuccessfully sought to defeat Gov. Brian P. Kemp of Georgia in his primary election in May. Mr. Kemp’s unwillingness to help overturn Mr. Biden’s win in the 2020 election drew Mr. Trump’s ire, and the Georgia governor is being compelled to testify before a special grand jury investigating election interference by Mr. Trump.
