"My comment on his compromised moral authority was based on America's reaction" to his rhetoric after the violence in Virginia, said Scott, the Senate's only black Republican.
The advice from Sen.
Scott, 51, the first African-American senator from SC and the only black Republican in the Senate, slammed Trump's second round of comments last month about the Charlottesville attacks that killed one woman and injured 19 others during a press conference at Trump Tower.
Scott's goal is that his meeting with the President on Wednesday will be the first step in that process, the source said.
He says the President was very receptive to what he had to say.
On Wednesday, Trump told Scott that he just meant to convey "that there was an antagonist on the other side" - to which Scott replied, "The real picture has nothing to do with who is on the other side".
Later in the day, White House press secretary Sarah Huckabee Sanders was asked whether Scott expressed displeasure about the president's handling of Charlottesville.
The resolution also acknowledged the deaths of two Virginia State Police officers whose helicopter crashed as they patrolled the Charlottesville protest.
President Trump dragged out the controversy, reading a statement criticizing the "KKK, neo-Nazis, white supremacists and other hate groups", then spending the next few days making it clear he resented being forced to do so.
Trump has been criticised for his response to the violence and rally, in which he asserted there were good people on "both sides" and bemoaned rising efforts to remove Confederate monuments as an attack on U.S. "history and culture". "We talked about ways to celebrate diversity - both within my administration and the country more broadly". The reported agreement enraged many Republicans, including Iowa anti-immigrant Congressmember Steve King, who retweeted an Associated Press report on the deal, adding, "If AP is correct, Trump base is blown up, destroyed, irreparable, and disillusioned beyond fix". Scott said given the time constraints and his ongoing work with the administration on HBCUs, that issue was not discussed in the Wednesday meeting.
Congressional Black Caucus chairman Cedric Richmond, D-La., also said he was gratified Trump and Scott sat down together.
"Anyone that expects an epiphany or a transformation to happen overnight because somebody walks in a room, I think, you don't understand human nature", Scott said of his discussion with Trump. In an interview on CBS' "Face the Nation", he said the best way for Mr. Trump to regain his moral authority on this issue would be spend more time interacting with African-Americans.
