“I don’t want to preempt their announcements, but I think you could piece it together based on who has testified before the committee on Jan. 6. Again, they’re not — these are related but separate investigations, and I think the DOJ is tracking who coming before Jan. 6 and who might have helpful information,” Farah Griffin told CNN’s John Berman on “New Day.” A spokesman for the US attorney’s office in Washington declined to comment. The criminal investigation into the attack on the US Capitol on January 6, 2021 and attempts to stop the transfer of power between the Trump and Biden administrations is the most extensive in the history of the Department of Justice. The Justice Department has already brought two top Pence aides before a federal grand jury, a move that signals its probe has reached into former President Donald Trump’s White House and that investigators are looking at conduct directly related to Trump and his closest allies ». efforts to sway the 2020 election. Marc Short, Pence’s former chief of staff, confirmed to CNN on Monday that he testified last week before a grand jury investigating the insurgency at the US Capitol. Pence’s former chief counsel, Greg Jacobs, also testified in recent weeks, according to CNN, a source close to the investigation. This story has been updated with additional developments.
