The shirtless FBI agent who began the investigation that ultimately led to Gen David Petraeus’ resignation as CIA director says the shirtless photo found in the email inbox of Tampa socialite Jill Kelley was a “joke” sent to dozens of friends and acquaintances. At first glance, there appears to be nothing particularly sexual about the photo as some had previously speculated.

A newspaper report describes the photograph of the shirtless FBI agent as silly but not scandalous.

The Seattle Times published the photo on Thursday. Along with Kelley, a reporter with the paper also received the photo all the way back in 2010 when it was first sent out. The picture was snapped following a “hard workout” with the SWAT team at MacDill Air Force Base. Posing in between two target dummies that look a lot like him, Frederick Humphries sent the photo with the following caption: “Which One’s Fred?”

The photograph helped land Humphries in hot water though. The FBI is investigating Humphries for talking with Republican lawmakers about the investigation into harassing emails that Kelley received from Petraeus’s biographer and mistress.

Petraeus resigned from the CIA last week after acknowledging an extramarital affair. The liaison was discovered during an FBI investigation of harassing emails allegedly sent by Petraeus’ biographer and mistress, Paula Broadwell, to Jill Kelley. Broadwell allegedly saw Kelley as a rival.

Is there anything inappropriate about the photo?
