U.S. Rep. Doug Collins's campaign recently ran into trouble with Sandy Springs-based United Parcel Service Inc. for a mailer attacking primary opponent Paul Broun that used images of the company's mail trucks, uniforms and famous old slogan.

The mailers, which circulated around the 9th Congressional District several weeks ago, highlighted past alleged ethics flaps associated with Broun's former Capitol Hill office -- and also photoshopped the former congressman into some great khaki shorts.

A spokeswoman for UPS said the company asked Collins' campaign staff to refrain from using its imagery and now-retired slogan, "What can brown do for you?"

"There is no legal action and to the best of our knowledge they pulled it out of circulation," said UPS spokeswoman Susan Rosenberg, who underscored that the company does not take positions on candidates for political office.

The Collins campaign said it purchased the license to use the photos for the "one and done" mailer but has complied with UPS' request.

Broun said the mailers represented "another one of (Collins') many misguided attempts to distract people from his voting record."

"His reckless use of UPS branding without getting their permission shows that he cares more about falsely attacking me than respecting businesses’ intellectual property," Broun said.

The back-and-forth is just the latest in a fiery 9th District primary campaign that's putting to the test what true conservatism means in the reddest congressional district east of the Mississippi River. Read more about the race here.
