Adequate words do not exist to describe the magnitude of this idiocy, as Arizona’s Sheriff Joe Arpaio cooperates with the far right’s craziest theocratic media site, World Net Daily, to launch an investigation into … wait for it … President Obama’s birth certificate.

Yes, really.

Sheriff Joe Arpaio of Maricopa County, Arizona has appointed a “cold case posse” to determine whether President Barack Obama was actually born in the United States.

The news was first reported by World Net Daily, an online publication that has doggedly pursued conspiracy theories about the president’s birth.

Sgt. Jesse Spurgin, a spokesman for the Maricopa County Sheriff’s Office, confirmed the news to The Daily Caller on Tuesday.

Spurgin explained that the tough-on-crime Arizona sheriff is tasking the posse with examining documents provided to Arpaio by author Jerome Corsi.

Jerome Corsi promotes insane conspiracy theories at Weird Nut Drooly (not just Birtherism, but the full panoply of wingnut delusions), he appears frequently on Alex Jones’s whacked out radio show, and he’s appeared more than once on the white supremacist radio show Political Cesspool.

That’s who’s calling the shots in Arpaio’s “investigation.” Unreal. Can sheriffs be impeached?
