Drake, Meek Mill Slam Leaking Of Young Thug's Jailhouse Phone Call

Drake and Meek Mill are angrily demanding justice for Young Thug  ... after an intimate video recording of him and his girlfriend speaking sweet nothings leaked from jail.

Social media began circulating the video of YT and Mariah The Scientist this week ... the two spend over a minute long telling one another how much they miss each other and admiring the Cuban necklaces Thug bought her.

On Thursday, Drake thrust the spotlight on Chief Judge Ural Glanville -- the judge presiding over YT's much publicized RICO trial -- and quite frankly asked him just what kinda circus he was running as ringmaster!!!

"This gotta be some form of jail misconduct," Drake wrote on IG. "You gonna drag this talented man then not be able to control your employees using his personal business for their own gain?

Drake continued ... "Somebody benefitted from this video even existing and that's shameful whole case is a wsh just 3 the guy and let him come home and continue bringing light to Atlanta ... Shit is disgraceful... is this a criminal case or atlanta social media promo Ural Glanville?"

Drake and Thug are tight but that doesn't mean his opinions of the case are biased -- the case has been subjected to several hijinks along the way.

Meek also supported Thug, demanding he sue for having his rights violated.
