But he also said Monday that he won't reconsider his decision against running for governor in 2010, even if he's holding the job.
The Statehouse continues to buzz with speculation about Sebelius. A senior Obama administration official has said the Kansas governor is a top candidate.
Parkinson said he and Sebelius have discussed ``every contingency,'' but he has no insight on whether she'll be appointed.

Last month, before speculation about Sebelius and the HHS job _ Parkinson announced he wouldn't run for governor in 2010.
He says he'll stick by that decision.
