In his first interview since his public ouster from the White House, Scaramucci told ABC's George Stephanopoulos that he would have advised Trump to make a more direct statement against white nationalism.
Trump on Saturday said "many sides" were responsible for the violence in Virginia.
Scaramucci said as White House communications director he "wouldn't have recommended" the statement Trump gave, and applauded National Security Adviser H.R. McMaster's characterization of the violence as terrorism.
"I think he needed to be much harsher as it related to the white supremacists and the nature of that", Scaramucci said during an interview Sunday on ABC's "This Week".
Lawmakers on both sides of the political aisle have called out Trump's apparent reluctance to specifically mention the white supremacist groups who gathered in Charlottesville for a "Unite the Right" rally. In remarks later Saturday afternoon, he called the clashes an "egregious display of hatred, bigotry and violence on many sides".
Scaramucci would not elaborate but said he spoke this week with President Donald Trump. The president is going to do what he wants to do, how he wants to do it.
SCARAMUCCI: I think people are probably reluctant to tell him the truth. He'll discuss what it's like to uproot your life to go work for the president only to be dismissed 10 days later because you couldn't resist making a joke during an on-the-record interview about Steve Bannon fellating himself. If the president really wants to execute that legislative agenda that I think is so promising for the American people, the lower-middle-class people and the middle-class people, then he has to move away from that sort of Bannon-bart nonsense, if you will.
Scaramucci also talked about that now-infamous bonkers phone call, saying, "I made a mistake".
"Well, I think the president knows what he's going to do with Steve Bannon", said the Mooch, declining to get into specifics.
