Dangers of Endorsing Product

A post at the excellent Project for Government Oversight blog reports on allegations that "a video in which 'Air Force pilots rhapsodize about the fastest, stealthiest, most advanced dogfighter ever built' " could be a violation of 5 C.F.R. § 2635.702, "Use of public office for private gain":

An employee shall not use his public office for his own private gain, for the endorsement of any product, service or enterprise, or for the private gain of friends, relatives, or persons with whom the employee is affiliated in a nongovernmental capacity, including nonprofit organizations of which the employee is an officer or member, and persons with whom the employee has or seeks employment or business relations.
