The 47-year-old hip-hop star is a long-time supporter of the 44th US President and has included him among his biggest career inspirations after being inducted into the Songwriters Hall of Fame.
In a long-winded Twitter post, Jay wrote: ''Thank you to all the people that have inspired me . Rakim KANE KRS chuck cube Jaz Em Andre Nas big PAC cole kendrick chance jayE ..wait,

The 'Empire State of Mind' hitmaker named his wife Beyonce among his list of favourite rap artists, while he also denied being drunk as he tweeted.
He continued: ''S**t did I say redman ? Ghost and Rae . Wu tang I beat Genius in a rap battle I think ha . Busta (him too) Treach . Thug . B a rapper too!

''Somebody find that reply I just hit please . I'm new on this . Anyway salute to anybody who made a song to feed their family or just vent . (sic)''
Jay - who uses Twitter sparsely - subsequently mocked his own social media skills, before hailing the influence of the former US President.
He said: ''F**k ..50 cent big L sho ag nice and smooth Joe and pun . diggable butterfly esp...beanie young chris freeway SP okay for real this time .
