Outing blogger Michael Rogers is stoking rumors that Senator Lindsey Graham is gay.

The 47-year-old gay rights activist, who was featured prominently in the outing documentary Outrage, has tweeted about his plans to make public revealing photographs.

Graham, a Republican from South Carolina, has been fighting the rumors for years. Most recently he told the New York Times: “Like maybe I'm having a clandestine affair with Ricky Martin. I know it's really gonna upset a lot of gay men – I'm sure hundreds of 'em are gonna be jumping off the Golden Gate bridge – but I ain't available. I ain't gay. Sorry.”

After Graham – a 55-year-old U.S. Air Force reservist and perennial bachelor – on Saturday denounced passage of a bill that repeals the military's ban on gay and bisexual troops serving openly, Rogers released a pair of tweets.

“I wonder if Lindsey Graham knows I have pictures of a man who spent the night at his house. pls RT,” Rogers, who claims a perfect outing record, messaged his followers.

About half an hour later, he added: “Just reached lawyer at home. Meeting set for Tues. on releasing pix of man who spent night at Lindsey Graham's.”

On Tuesday, Rogers clarified his messages, saying in a blog post that he's “working on it.”

The next step “is to contact Lindsey Graham's office (as instructed by my counsel) to show them what I have and to see if they want to make an on the record comment.”
