If you're connected to setting/regulating US monetary or fiscal policy in any way, you can't:
-short (bet against) the market
-direct your investments
-communicate with the manager of your investments regarding those investments for the duration of your position
Look at market fluctuations & comments in the media over the past month, and you'll find this accurate.
Or just follow politics.
Another sure fire way to weed out corrupticrats who see public office as an opportunity for windfall rather than civic duty.
