The host was dropped after making "racially-charged and hate-filled remarks on social media," the satellite radio company said.
SiriusXM has fired Opie and Anthony host Anthony Cumia after he posted a series of racist remarks on Twitter earlier this week.
Patrick Reilly, senior vp of communications at the satellite radio company, wrote in a statement that the 53-year-old DJ's posts were "abhorrent" and the host was fired on Thursday.
"SiriusXM has terminated its relationship with Anthony Cumia of the Opie & Anthony channel. The decision was made, and Cumia informed, late Thursday, July 3 after careful consideration of his racially-charged and hate-filled remarks on social media," Reilly stated. "Those remarks and postings are abhorrent to SiriusXM, and his behavior is wholly inconsistent with what SiriusXM represents."
"Sirius decided to cave and fire me. Welcome to bizarro world. Fired for shit that wasn't even on the air & wasn't illegal. So, who's next?" the Opie and Anthony host wrote on Twitter on Friday, adding in a subsequent tweet: "After the wkend, I'll have a better idea of things. F--- Sirius. I'll pop on the Compound show next week and discuss this with TOTAL FREEDOM."
Earlier in the week, Cumia had tweeted about an incident where he alleged that an African American woman attacked him while he was taking pictures in New York City. The host used offensive words and made racist statements in the Twitter tirade, also adding: "She's lucky I was a white legal gun owner or she'd be dead. Then 5 blacks started giving me shit!"
The pair have a long history of controversy, and were suspended from Sirius XM for a period of 30 days 2007 over the controversial comments of a program guests they called "Homeless Charlie." Prior to that, the duo was fired over a broadcast on Boston station WAAF-AM, a hoax in which the DJs claimed the Mayor had died in a car accident. Following their dismissal from WAAF, they secured placement on New York-based rock station WNEW-FM.
