Now I'm Interested

I hadn't been following the Sestak thing (it doesn't strike me as that unusual that Parties try to shuffle personnel around to put their best candidates forward), but this from the Prez' presser yesterday caused me to say Hmmm.
President Barack Obama said Thursday that "nothing improper happened" regarding allegations that the White House offered Rep. Joe Sestak a job to get out of the Pennsylvania Democratic Senate primary.

Speaking at a press conference in the East Room, Obama said his administration would release an official response to the claim very soon.
So the President's statement is not the White House position?
