In April, Ali Alexander, a prominent “Stop the Steal” organizer, revealed that he had been served with his own grand jury subpoena, asking for records about people who organized, spoke at or provided security for pro-Trump rallies in Washington after the election, including Mr. Trump’s incendiary event near the White House on Jan. 6.
Mr. Alexander’s subpoena also sought records about members of the executive or legislative branches who may have helped to plan or execute the rallies, or who tried to “obstruct, influence, impede or delay” the certification of the 2020 presidential election.
Last week, word emerged that the same grand jury, sitting in Washington, had more recently issued a different set of subpoenas requesting information about the role that a group of lawyers close to Mr. Trump may have had played in a plan to create alternate slates of pro-Trump electors in key swing states that were won by Joseph R. Biden Jr.
The lawyers named in the subpoena included Mr. Trump’s personal attorney, Rudolph W. Giuliani; Jenna Ellis, who worked with Mr. Giuliani; John Eastman, one of the former president’s chief legal advisers during the postelection period; and Kenneth Chesebro, who wrote a pair of memos laying out the details of the plan.
Those subpoenas also requested information about any members of the Trump campaign who may been involved with the alternate elector scheme and about several Republican officials in Georgia who took part in it, including David Shafer, the chairman of the Georgia Republican Party.
Mr. Navarro’s subpoena, by his own account, was issued by a different grand jury.
In the draft of the suit he said he intends to file, he argues that only Mr. Trump can authorize him to testify. He asks a judge to instruct Mr. Graves, the U.S. attorney in Washington, to negotiate his appearance with Mr. Trump. Mr. Navarro cites Mr. Trump’s invocation of executive privilege over materials related to the attack on the Capitol.
“The executive privilege invoked by President Trump is not mine or Joe Biden’s to waive,” Mr. Navarro writes. “Rather, as with the committee, the U.S. attorney has constitutional and due process obligations to negotiate my appearance.”
