But we also need to know whether Giuliani did more than that. What did he know? And when did he know it? With whom did he speak?
Of course, authorities should not confine their investigation to whether Giuliani communicated with riot revelers.
They also ought to learn if he spoke with late-term Trump appointees at the Department of Defense, Homeland Security and the Department of Justice in the days leading up to the insurrection.
This is another potential fertile ground of investigation because members of Congress have questioned whether the Capitol was secured properly.
After all, Trump and his followers did not hide the fact that they planned to stage a "wild" event in D.C. on Jan. 6 - wild being Trump's word of choice on his now shut Twitter account.
Incoming Biden administration brass may want to please the boss and "move on" with the business of governing. But protecting our democracy is a sacred act of governing.
We need to know what happened.
We need to see people held accountable for trying to destroy our way of life.
