House Oversight and Government Reform Committee Chairman Darrell Issa, R-Calif., lauded Rep. Henry Waxman, D-Calif., who announced his retirement today, calling his Golden State Democratic colleague an innovator who expanded the scope of congressional investigatory powers.

While conceding they rarely say eye-to-eye on politics, Issa praised Waxman's 2007-2009 committee chairmanship for giving the panel new tools like the use of subpoenas for closed-door depositions as well as an expanded mandate.

"A number of issues he doggedly began to follow during his two years as Chairman, such as the use of the White House Office of Political Affairs to advance partisan political agendas with taxpayer funds, the over-classification and pseudo-classification of information to hide embarrassing government blunders, and the problematic use of non-official e-mail accounts for official government business remain on the Committee’s agenda today. Even the Committee’s name reflects a change made under Chairman Waxman’s time leading the panel," Issa said. It was previously just the House Government Reform Committee.

Issa ended his statement wishing Waxman well during his "well-earned retirement."
