It’s obvious by now that Jeffrey E. Neely was not running the tightest ship over at the General Services Administration. Not only did he organize a lavish $823,000 Las Vegas retreat that has mired his organization in scandal, he brought along his wife on official trips at taxpayer expense. Neely’s wife, Deborah, also handled party arrangements and directed event planners to spend government money. An investigator called her the “first lady of Region 9,” the region Neely covered. The Justice Department is investigating the GSA’s alleged misconduct. On Monday Neely invoked the Fifth Amendment in front of the House Oversight and Government Reform Committee.
