Tom DeLay, the former House Speaker who began his working life in the Houston suburbs exterminating ants and roaches, made his name in Congress exterminating his opposition, and exterminated himself in a cloud of ethics scandals, has wrapped up his anihilatory political career by exterminating his paper trail. DeLay's former aides, who recently went to work for his interim Republican replacement, Shelley Sekula-Gibbs, deleted unnamed (and presumably sensitive) office files this week before quitting en-masse on Tuesday. A DeLay spokesman told the Times the trashing of files and scrubbing of hard drives was standard operating procedure for congressional transfers of power. Still, Sekula-Gibbs, who is occupying the seat until Democratic victor Nick Lampson is sworn in this January, has asked Congress to investigate the file deleting. You've got to hand it to the Exterminator for his skill creating scandalseven as his political life is upside down and twitching.
