I will pause here to offer this: The oath Nancy Pelosi swore to when she took office as a member of the House of Representatives.
"I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter: So help me God."
The central, nay only, requirement of this oath is the preservation of the rule of law, to defend the constitution of the United States. This is what Americans have fought and died for since it's ratification. And note that it includes domestic enemies, a phrase that was added after the civil war to remind members that not just foreigners can endanger the liberties that the constitution promises us all.
As long as Nancy Pelosi hold the office of Speaker of the House, every time she appears in public someone needs to stand before her and say:
Madame Speaker, The President of the United States and the Vice-President of the United States have, by their own admission, broken the laws of the United States to a level which may be construed as Treason. They have admitted to actions which the world has deemed War Crimes. Why have you not followed the oath of office to which you swore, and brought these crimes before the body of which you are leader? Why have you shirked your duty and ignored your oath and not sought the impeachment of these officials as is required by the Constitution? Why have you stated that you will not even consider impeachment even though the oath you swore requires you to? How can you stand before the people of the United States and the world and refuse to do that to which you swore?
If Nancy Pelosi finds that she can not appear in public without someone asking her these simple questions maybe the time will come where she actually has to answer these questions.
