The FBI is investigating Stephen Colbert following a controversial joke the Late Show host made in which he referred to President Donald Trump’s mouth as a storage device for Russian President Vladimir Putin’s penis.

FBI officials were deeply unsettled by Colbert’s joke, and are demanding to know how he came to know classified U.S. intelligence.

Trump took to twitter where he denounced the joke and vowed to uncover the source of the leak.

According to an official with the FBI, Colbert proved resilient to even advanced interrogation.

Colbert reportedly recited The Silmarillion while being subjected to bamboo torture.

The Kremlin has denied the allegations, insisting that Putin has seen tapes of where that mouth has been.
