In the dozens of framed images and newspaper clippings covering the walls of his office in downtown New York City, Al Sharpton is pictured alongside presidents and leading protests.
He has spent decades campaigning and is perhaps the most famous civil rights activist in the US today.
Many of those clippings on the wall relate to one moment in May 2020 – the murder of George Floyd.
Speaking to Sky News ahead of the five-year anniversary of that moment, Mr Sharpton remembered the combination of “humiliation and deep anger” he felt seeing the footage of Mr Floyd’s death that swept the world.
“The more I watched, the more angry I felt,” he said.
Mr Floyd was murdered in Minneapolis by Derek Chauvin, a 44-year-old white police officer.
Mr Floyd had been arrested after a store clerk reported he had made a purchase using counterfeit money.
Chauvin knelt on Mr Floyd’s neck for over nine minutes, while he was handcuffed and lying face down in the street.
‘A seismic moment’
For Mr Sharpton, who has marched with countless other families, this felt different because it was “graphic and unnecessary”.
“What kind of person would hear somebody begging for their life and ignore them?” he said.
“I had no idea this would become a seismic moment,” he continued.
“I think people would accuse civil rights leaders, activists like me of being opportunistic, but we don’t know if one call from the next one is going to be big, all we know is we have to answer to the call.”
Trump ‘pouring salt on the wounds’
Mr Floyd’s death took place during Donald Trump’s first term in the White House.
During Trump’s second term, his administration has moved to repeal federal oversight plans for the Minneapolis Police Department – a move originally supported by Joe Biden’s administration.
Mr Sharpton believes Mr Trump and the Department of Justice have purposely timed this for the 5th Anniversary of Mr Floyd’s Death.
“It’s pouring salt on the wounds of those that were killed, and those that fought,” he said.
“I think Donald Trump and his administration is actively trying to reverse and revoke changes and progress made with policing based on the movement we created after George Floyd’s death, worldwide.”

Mr Sharpton still supports George Floyd’s family and will be with them this weekend in Houston, Texas, where many of them will mark the anniversary.
He said the legacy of Mr Floyd’s death is still being written.
Evoking the civil rights movement of the 1960s he said: “The challenge is we must turn those moments into permanent movements, it took nine years from 1955 to 1964 for Dr [Martin Luther] King in that movement to get a Civil Rights Act after Rosa Parks sat in the front of a bus in Montgomery.
“We’re five years out of George Floyd, we’ve got to change the laws.
“We can do it in under nine years, but we can’t do it if we take our eye off the prize.”
