How about this?
An alternate #January6thCommission. Created by executive order with only the two co-chairs appointed by Pres. Biden: Pres. George W. Bush(R) and Pres. Barack Obama(D). Bush and Obama pick the remaining members. Mix of public & private funding. Commission determines end date.
The question does come up…..
Such a body could not compel anyone to come in for questioning….
And a President couldn’t do so to members of Congress due to seperation of power…
