Really, What is Going On At OPM?

I'm waiting for answers on why he did this, but apparently President Obama has appointed an acting Office of Personnel Management director, Kathie Ann Whipple, previously the agency's deputy general counsel. The full announcement is below the jump.

A couple of things strike me as strange about this. 1) If John Berry is, in fact, going to be the nominee, why not just appoint him? 2) It was never clear what President Bush did when he "designate[d] Acting" Michael Hager at the OPM job. It was never clarified whether Hager had a set term, under what circumstances he could be dismissed, etc. 3) The Obama team has normally announced all appointments. I can't recall if any of them have been acting appointments. So it seems unusual that he would make an acting appointment here, and that OPM would announce it, rather than the Obama camp.

You'll get details as I get them. Any insights would be helpful, too!
