In announcing her departure from his Cabinet, President Obama offered effusive praise of Health and Human Services Secretary Kathleen Sebelius on Friday. Of Sebelius, Obama said:

After five years of extraordinary service to our country -- and 7.5 million Americans who have signed up for health coverage through the exchanges -- she’s earned that right.  I will miss her advice, I will miss her friendship, I will miss her wit.

Of course, Sebelius' legacy as the chief implementer of the Affordable Care Act, the signature piece of legislation passed during Obama's presidency, is far more mixed. Obama's face in the picture above, perhaps more than any words he said, tell that story.
