(A far better history of the tensions between between Pusha and Wayne can be found here.)
Pusha T, formerly of the Clipse, is these days a solo artist on Kanye West's GOOD Music imprint on Def Jam, whose parent company is Universal; he's been unsuccesfully trying to spark a beef with Lil Wayne since 2006 or so (y'know, the exact moment that white indie rock bloggers fell in love with the Clipse and started jocking coke rap). Back then, Pusha was streamed that Wayne was wearing the same clothes as the Clipse, which is kind of Oscar night of him. But he just recently started it all back up, going after Wayne and Drake—who is an artist signed to Wayne's imprint on Cash Money Records, who are also part of Universal. The reason I point out all this about their record companies in such, is because rappers, to paraphrase Shabazz, really believe in their labels.

Pusha, in his song "Exodus 23:1," taunts Drake about his record deal:

contract all fucked up/I guess that means you all fucked up/You signed to one nigga, that’s signed to another nigga, that’s signed to three niggas/Now that’s bad luck

Ironic, seeing as Pusha, whose old group was famously plagued by label problems (crackers not playing fair at Jive and all) is not in a situation that is at all different. In fact, what's really bad luck, historically, is being fucking signed to Kanye West's label—while artists on Lil Wayne's label, such as Drake and Nicki Minaj, have seen mega-success.

To me it, like just about every so-called beef that happens nowadays, all sounds like a pre-fab wrestling storyline cooked up in some Universal boardroom to trick teenagers into buying mp3s. The OG Andy Milonakis treats the beef with all the seriousness it merits:
