Alex Jones waves gun at Piers Morgan in Conan O'Brien spoof - video
In a clip from the interview showed on last night's Conan, a firing gun was digitally inserted into Jones's hand as he continued his rant.
Jones had supported a petition to deport Morgan back to the UK for his arguments in favour of gun control.
The petition later received an official response from the White House after passing the 25,000-signature threshold.
"It is worth remembering that the freedom of expression is a bedrock principle in our democracy," noted spokesperson Jay Carney.
Jones later claimed that he feared for his life after his rant on CNN's Piers Morgan Tonight, calling New York City Mayor Michael Bloomberg "total mafia".
