Fox News host Sean Hannity on Tuesday promoted a bizarre conspiracy to his millions of loyal followers involving “secret sperm cells” in the official portrait of President Barack Obama.

“Obama’s portrait—a stark contrast to predecessors with inappropriate sexual innuendo,” the Fox News host tweeted, linking to an article on his website written by “Hannity Staff.”

“PORTRAIT PERVERSION: Obama Portrait Features ‘SECRET SPERM,’ Artist Joked About ‘Killing Whitey’” the headline read.

“Controversy surrounding Kehinde Wiley’s wildly non-traditional portrait of the commander-in-chief broke out within minutes of its unveiling,” Hannity’s website alleges, “with industry insiders claiming the artist secretly inserted his trademark technique — concealing images of sperm within his paintings.”

According to the Daily Beast:

It appears that the whole “sperm” theory originated on—where else?—4chan, where a thread was posted on Monday proclaiming, “Official Portrait of Obama has SPERM on his face!!!” That post just happened to include the same close up of Obama that Hannity used on his site.

Hannity has previously claimed with no evidence whatsoever that President Obama was not born in the U.S., that he is in cahoots with the entire “liberal media,” and that under his watch, a Democratic National Committee staffer was killed because he supposedly gave emails to WikiLeaks, reports TheWeek.
