Although Stevens was too ill to appear in the Senate on March 3, when the managers requested that Johnson be summoned (the President would appear only by his counsel, or defense managers), he was there ten days later when the summons was returnable.
Deși Stevens era prea bolnav pentru a apărea în Senat pe 3 martie, atunci când acuzatorii au cerut convocarea lui Johnson (președintele era reprezentat doar de avocații săi), el a fost acolo zece zile mai târziu, când convocarea a fost returnabilă.
