On July 3, 2014, Cumia was fired by SiriusXM, after making a series of tweets, that they deemed racist, following an alleged off-air incident with a black woman on the street.
 Cumia tweeted that he was punched by the woman while attempting to take a picture in Times Square.
 The tweets were described by Sirius XM as "racially-charged and hate-filled".
 Cumia stated on the Saturday, July 12 episode of "Red Eye w/Greg Gutfeld" that he was not going to apologize for the incident.
 At the time of Cumia's firing SiriusXM made no comment as to Hughes' possible future with the company at that time.
 Cumia gave his blessing for the Sirius XM show to continue without him, acknowledging Hughes and Norton's obligation to fulfil their contract with SiriusXM.
 A relaunched "Opie with Jim Norton" resumed on July 14, 2014 with Hughes and Norton discussing the incident and noting that The Opie and Anthony Channel was renamed SiriusXM Talk, along with various other alterations by the company in light of the firing.
 In October 2014, Hughes and Norton signed a new contract to continue the SiriusXM show, which appears on the rebranded Opie Radio channel.

The Opie & Anthony Show Knuckeheads, also known as ""The O&A Army"" or ""The Pests"," were names used to describe fans and listeners of The Opie & Anthony Radio Show who took a proactive approach to the show's content and promotion.
 As opposed to just casually listening, these fans were involved in listener events, promoting the show, on-air segments, and listener stunts/pranks.
 They are jokingly known by the hosts as a collection of "computer nerds" and "failures", with the implicit recognition that these devotees relate well to the hosts themselves.
 Forbes Magazine has recognized "The Pests" as a major source of viral marketing for the show, facetiously suggesting that Anthony Cumia be nominated as CMO of XM Satellite Radio for his role in encouraging and leading the Pests.
