Here are a few interesting stories and some brief commentary:
2) On briefings:
Former U.S. Representative Jane Harman, a Democrat who served on every major House security committee before resigning from Congress in 2011, said getting the right briefer can make a big difference in how much lawmakers learn.
“Sometimes these briefings are a game of 20 questions. If you don’t ask exactly the right question, you don’t get the answer,” said Harman.
Note that it may be worth considering the combined implications of 1) and 2), given that briefings often come from bureaucrats.
3) “On occasion, the most striking evidence of power and influence is the invisibility of its source.” From Sailer.
