Yep, President Bush has nominated EPA Administrator Mike Leavitt to be HHS Secretary. What this means for EPA is very unclear. The agency was adrift under Christie Todd Whitman, but Leavitt had begun to right the ship. Leavitt had a superior understanding of both environmental policy and environmental politics than Whitman. Moreover, unlike his predecessor, he didn’t allow his agency to undermine the White House. No word on his possible replacements.
