Senator Roberto Arango of Puerto Rico has resigned after being accused of posting naked pictures of himself on mobile gay male hookup site Grindr, the AP reported.

The AP story quotes Senate President Thomas Rivera Schatz saying Arango presented his letter of resignation after a meeting over the weekend.

Arango is a member of the Republican Party. He vice-chaired the 2004 reelection campaign of George W. Bush. In 2009, he voted in favor of a measure that sought to constitutionally ban gay marriage in Puerto Rico.

The Puerto Rican TV show Dando Candela presented the conservative lawmaker with a photograph of a man, naked except for a pendant necklace, whose face was obscured by an iPhone as he snapped a photo of his reflection in a mirror.

Arango didn't exactly deny he was the subject in the photograph: “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.”

“It would be my pleasure to tell you I'm the person in this photograph, but honestly I don't remember,” he said with a big smile. (The video, in Spanish, is embedded in the right panel of this page.)

When the reporter asked if he owned an iPhone, Arango said he used an iPhone and a Blackberry.

In a second report, the outlet dug up photos of Arango wearing a similar necklace as the one in the photograph.

In another photo, allegedly from the same Grindr account, the man bends over on a bed to snap a shot of his naked bum.

Arango is a graduate of Louisiana State University. He and his wife have one child.
