Rachel Maddow on Friday examined Jerome Corsi's new conspiracy theory that President Barack Obama is secretly gay.

On her MSNBC The Rachel Maddow Show, Maddow told viewers that Corsi, author of Where's The Birth Certificate, began promoting the theory after Obama released his long form birth certificate.

Corsi “needed a new reason to get out of bed every morning. And Jerome Corsi has now found one,” Maddow said. “Did you think they would give up on this?”

Maddow shared with her audience Corsi's supposed evidence.

“It was preposterous to the people I knew then to think Obama was going to keep his gay life secret,” Kevin DuJan, who reportedly worked as a gossip columnist in Chicago, is quoted as saying in one of Corsi's articles published on World Net Daily. “Obama used to go to the gay bars during the week, most often on Wednesday, and they said he was very much into older white guys.”

Corsi also claims that a ring Obama wore while in college must mean he was secretly gay married to his Pakistani roommate.

“Gay, gay, gay, gay, gay, gay. World Net Daily says so,” Maddow said. “Now the president is going to have to unveil his straight certificate – the long form one.”
