Bill O'Reilly isn't one for nuance. Earlier this year, the Fox News demagogue said that hip-hop is responsible for the decline of Christianity in America. “People of faith are being marginalized by a secular media and pernicious entertainment,” O'Reilly said. “The rap industry, for example, often glorifies depraved behavior, and that sinks into the minds of some young people–the group that is most likely to reject religion." Killer Mike, a respected political voice in his own right, fired back the next night on Real Talk With Bill Maher, calling him "full of shit" and lamenting that white people take him seriously. Today (July 13), in an interview with DJ Whoo Kid--with his Run the Jewels partner El-P in tow--Mike really let loose. The Atlanta rapper called O'Reilly a "cocksucker" and mocked his holier-than-thou posturing in light of domestic violence allegations against him that surfaced during a custody battle.

After linking up for Mike's 2012 solo album, R.A.P. Music, the pair has been inseparable in the booth and on festival stages. Each installment of their Run the Jewels collaboration dropped to critical and popular acclaim, and they've become one of the most raucous, in-demand live acts in hip-hop. During the interview, El also cracked that he's the "white Lil Cease," after he played hype man during Nas' surprise appearance at a Run the Jewels show. The pair had plenty of laudatory things to say about the Queens rapper, who serves as their label boss on Mass Appeal.
