As Politico reported Tuesday, former Nebraska senator Chuck Hagel was paid $120,000 in 2012 to work as a "senior adviser" to Gallup, the Omaha-based polling and research firm. Gallup won't explain what services or expertise Hagel actually provided.

Lauren Kannry, a spokeswoman for Gallup commented in an email to THE WEEKLY STANDARD that Hagel was paid as "one of more than 20 outside senior advisors and senior scientists that provide Gallup with expertise on a wide variety of subjects ranging from global workplace research to healthcare to advanced analytics of global wellbeing."
