"He has to move away from that sort of "Bannon-bart" nonsense", Scaramucci said, apparently combining Bannon's name with Breitbart, the website that Bannon ran before joining Trump's campaign a year ago.
"He likes doing the opposite of what the media thinks he's going to do", Scaramucci said. "He's got to be more into where the moderates are and the independents are, George, that love the president".
Former White House communications director Anthony Scaramucci hit at Steve Bannon for his controversial views a day after a white nationalist rally in Charlottesville, Virginia, descended into violence.
The responses from both Scaramucci and McMaster came the day after Axios reported that Trump suspected Bannon has been leaking damaging information about White House colleagues, and was weighing firing the political adviser.
"I think there are elements inside of Washington, also inclusive in the White House, that are not necessarily abetting the president's interests or his agenda".
Mr Scaramucci made the claims in an interview with ABC as he spoke publicly for the first time following his dismissal by the President after just 10 days in the job.
Asked if he believed "Bannonbart" had an influence on President Trump's thinking, Scaramucci replied: "I would say no".

He claims he was sacked after Swift falsely accused him of grabbing her and he is seeking up to $3 million in damages. Swift and Mueller are both expected to testify, along with Mueller's former boss and members of Swift's entourage.
He also insulted chief strategist Steve Bannon in a profanity-filled rant.
Like many others, Scaramucci told host George Stephanopoulos that he disagreed with Trump's weak and freaky statement on the outbreak of white supremacist violence over the weekend in Charlottesville, Virginia. The president has a very good idea of the people that are undermining his agenda that are serving their own interests.
Scaramucci blasted Bannon in an oft-quoted New Yorker interview that featured the man known as "the Mooch" uttering blue language.
The "many sides" part is what drew a strong rebuke from those who believed the president needed to specifically lay blame at the feet of the "alt-right" gathering to protest the removal of a statute of Confederate Gen. Robert E. Lee.
Republicans and Democrats immediately criticized Trump's lackluster condemnation. "I want to be totally accountable for what I did, and obviously I paid the consequences of having that sort of conversation with him".
"I've never sat down with Steve Bannon and said, 'Hey, are you a white nationalist or a white supremacist?' But I think the toleration of it by Steve Bannon is inexcusable", Scaramucci said.
"Can you and Steve Bannon still work together", Todd asked.
