Rob Blair, the majority clerk on the House Energy and Water Appropriations Subcommittee, is leaving the panel for the same spot on the Defense Appropriations Subcommittee. Blair follows Rep. Rodney Frelinghuysen (R-N.J.), who shifted to the top spot on the Defense Appropriations Subcommittee two years ago after helming the Energy and Water panel. Blair has been the Republican clerk on Energy and Water since 2008, taking the majority in 2011 when Republicans took control of the House. It is unclear who will replace him on the committee.
