EPA Air Quality Chief Resigns Over Ethics Investigation

So little time, so much damage done. That's the legacy left by Bill
Wehrum who spent only one and a half years as the U.S. Environmental
Protection Agency's (EPA's)
top air quality official before announcing that he will step down this
weekend under the cloud of a federal ethics investigation over possible
conflicts of interest. His resignation follows conflicting statement he
made to Congress about his industry connections, according to Politico.
