Lawmaker's Nude Photos on Gay Site: I'm Documenting My Weight Loss (WARNING -- Graphic)

Here we go again -- another lawmaker has been caught up in a naked photo scandal.

This time it's Puerto Rican Sen. Roberto Arango, whose alleged nude photographs on the gay meet-up site Grindr were exposed last week.

According to Hispanic gossip site Guanabee, a Puerto Rican TV station first aired the pictures last Friday, supposedly downloaded from the popular cruising app.

One photo thought to be of Arango depicts a bare-chested man posing in front of a mirror, using his cell phone to take the picture -- the same style once favored by former U.S. Reps. Anthony Weiner and Christopher Lee.

Another photograph is a direct shot of Arango bending over, exposing his rear end. (Photo below -- WARNING: May be considered graphic.)

When asked about the pictures by Puerto Rican media, Arango neither confirmed nor denied they were his. Instead, he said this:

"You know I've been losing weight. As I shed that weight, I've been taking pictures. I don't remember taking this particular picture but I'm not gonna say I didn't take it. I'd tell you if I remembered taking the picture but I don't."

Arango served as vice chair of Puerto Rico's Bush-Cheney 2004 re-election campaign.
