Another One Bites the Dust

I hope someone is keeping a tally of how many Obama appointees have fallen out of contention for his "positions" within his administration.

But, yet another one bites the dust:

President Obama's nominee, Jon Cannon, for U.S. EPA's second highest post abruptly pulled out of the Senate confirmation process today because of an investigation into the nonprofit group where he once served on the board of directors.

Is anyone associated with this administration clean?
