HCR Update from Mark Sanna: Mitt Romney's choice of Michael O. Leavitt as his transition chief has spurred loud opposition from some conservatives over Mr. Leavitt's support of a crucial part of President Obama's health care plan.

Bush's cabinet, is now a health care consultant who advises states on how to implement Mr. Obama's health law.
