He's highly unlikely to release any details on Alien life-forms for fear of 'outing' himself!
It's a well-guarded secret that since Donald the Trumpeter was abducted for advanced sexual experimentation, he wasn't the same man when they returned him to Earth.... Oh Not at all!
You have to understand that following several foiled attempts of said Aliens to populate Earth, they have changed their modus operandi. Since the landing accident at Roswell (a small 'bottle-to-throttle' indiscretion) & the secluded landing-spot at Woodbridge, UK. incident, where they alighted in the middle of the weekly dogging-meet, a quantum change of thought was initiated.
With the dubious Trump inauguration completed the final piece of the Alien jigsaw is now in place, with several members of the Iranian Government, Ayatollah Khamenei & Akbar Hashemi Rafsanjani for sure plus Vlad Putin all being alien clones, their job is done!
All they do now is have a quick 'Alien Siesta' whilst these muppets orchestrate Armageddon, then just move-in unopposed? Some say that 'Melania' is a product of Putin's stag-night in Kiev, others say she's a gift to DT. from a 'stock' of Vlad's 263 cousins, sisters, half-sisters & sheep! All we know is...she's fit!
PS:- Anybody got Ridley Scott's phone number??
