the practical effect, not to ignore any of it, i gave you my joke with mark morgan and matt almonds, there is sort of a time in service element that there is a benefit to being in a role, or in a department longer. kevin mcaleenan brought years and years of experience to the acting secretary role, and by way of example, it is not that there are not other benefits. me coming from the outside, i think i have changed how uscis operates and some of the culture they're pretty quickly. that is a benefit. but you know, there are trade offs to both, but in terms of getting work done. i have not experienced a problem either being an acting or working with fellow acting director second missionaries. >> there is technically a rule about senate approval, i think it is the tsa administrator, this entire table can correct me if i am wrong. doesn't that limit the political side of -- you know, naming the next secretary, when you have the limitations of senate republicans who have expressed, for instance, but they don't -- they haven't supported her candidacy so far. how do you pack who is next? >>
