exactly what happened here. Trump can claim stupidity, but it won't change the offense...only, perhaps, the sentence he receives.
While DJT has a multitude of mental and ethical 'deficits', no one who resides in the Oval Office for four years can plausibly claim they don't know what a Top Secret/SCI document is, or why it is normally so protected....
This brings us to your level of competence and judgement...do you give DJT a "Pass" for having TS/SCI documents in his Mar-a-Lago home?
