Recess appointments
These are an anachronism at best; legislation should be proposed immediately to get rid of them.
It can't be done with legislation; it will take a constitutional amendment:
Article II, Section 2.3. The President shall have power to fill up all vacancies that may happen during the recess of the Senate, by granting commissions which shall expire at the end of their next session.
No doubt it is an anachronism, based on a slower moving world, but it can't be changed by legislation. So be prepared to find out the day after Congress recesses that Gonzales has resigned and John Yoo has been appointed Attorney General.
