longstanding department policy, a present president cannot be charged with a federal crime while is he in office. that is unconstitutional. charging the president with a crime was, therefore, not an option we could consider. brian: so when bob barr says -- bill barr says bob mueller told me three separate times that wasn't the only reasonable reason we are charging him but something he kept in mind. bob mueller went out of the way to write that in the script to make this clear that's the only reason we took to have the table. the judge just told us if you look at bill clinton what happened in 2,00 2000. even if he kept under seal. part of the department of justice and by regulation was bound by the department policy charging the president with a crime was therefore not an option to consider. so if you can't consider charging him, but you didn't exonerate him and he made that clear of obstruction i guess that's so.
