I don't know how much more clear the attorney general can make it. He will "hold accountable" anyone who attempted to interfere with the transfer of power. Via NBC News:

The Justice Department plans to prosecute anyone who was “criminally responsible for interfering with the peaceful transfer of power from one administration to another,” Attorney General Merrick Garland said Tuesday, speaking more expansively than he has previously about a federal criminal investigation that appears to have moved far beyond the rioters who attacked the Capitol.

And just to make sure the people in the cheap seats can hear, Lester Holt asked him again:

“The indictment of a former president, and perhaps a candidate for president, would arguably tear the country apart,” Holt said. “Is that your concern as you make your decision down the road here, do you have to think about things like that?”

Garland replied: “We intend to hold everyone, anyone who was criminally responsible for the events surrounding Jan. 6, for any attempt to interfere with the lawful transfer of power from one administration to another, accountable. That’s what we do. We don’t pay any attention to other issues with respect to that.”

Holt followed up, asking whether, if Trump were to become a candidate for president again, “that would not change your schedule or how you move forward or don’t move forward?”

Garland responded: “I’ll, say again, that we will hold accountable anyone who was criminally responsible for attempting to interfere with the transfer, legitimate, lawful transfer of power from one administration to the next.”
