Sen. George Voinovich (R-Ohio) has blocked floor action on the nomination of Robert Perciasepe to be the Environmental Protection Agency's deputy administrator. The Environment and Public Works Committee on July 15 cleared Perciasepe, a former top EPA water and air official, for the No. 2 post. But Voinovich put a hold on the nomination, citing concerns over EPA’s analysis of a climate bill the House passed in June.
