Last month, about 40 subpoenas were issued to a large group of former Trump aides — among them, Mark Meadows, Mr. Trump’s final chief of staff; Dan Scavino, his onetime deputy chief of staff for communications; and Stephen Miller, Mr. Trump’s top speechwriter and a senior policy adviser.
It is likely that Mr. Trump will try to assert some form of privilege over the testimony of each of those potential witnesses in a bid to narrow what the grand jury can hear about him.
Even as the Justice Department presses forward in seeking evidence about Mr. Trump’s involvement in the events leading up to the Capitol attack, the House committee investigating Jan. 6 is also continuing to hear from witnesses.
On Tuesday, Hope Hicks, a former top aide to Mr. Trump, testified for about four hours in front of the panel, according to two people familiar with the matter.
The interview of Ms. Hicks, which was conducted virtually, came late in the committee’s 16-month investigation and after it has most likely concluded holding public hearings. Still, the members of the panel have kept pushing for more information about Mr. Trump’s state of mind in the final weeks of his administration and how often he was told there was no evidence of a stolen election.
During a meeting with Mr. Trump, Ms. Hicks told the former president that she had seen no evidence of widespread fraud that could overturn the results of the election, according to the book “Confidence Man” by Maggie Haberman, a reporter for The New York Times.
“You’re wrong,” Mr. Trump replied, hoping to scare others out of agreeing with her.
Throughout August, the panel interviewed top administration officials, including Robert O’Brien, Mr. Trump’s former national security adviser; Elaine Chao, the former transportation secretary; and Mike Pompeo, the former secretary of state. Investigators asked questions regarding reports of discussions about invoking the 25th Amendment to remove the president from office, among other topics.
