The brother of George Floyd, whose killing by police sparked worldwide protests against racism, made an emotional plea on Wednesday to the US Congress to “stop the pain” and pass reforms that make officers accountable for brutality.

One day after burying his brother in the US city of Houston, Philonise Floyd appeared in person before a House hearing, where he described the anguish of watching a viral video of George’s death and demanded lawmakers act to fix law enforcement problems including systemic racism.

The younger Floyd said: “I’m here to ask you to make it stop. Stop the pain.

“I can’t tell you the kind of pain you feel when you watch . . . your big brother, who you looked up to your whole entire life, die – die begging for his mom.

“He didn’t deserve to die over $20,” he said, referring to his brother’s alleged effort to use a counterfeit bill before his arrest.

“I’m asking you – is that what a black man is worth, $20?” Floyd asked. “This is 2020. Enough is enough.”

Floyd, who wore an anti-virus mask bearing an image of his brother, wiped his forehead and fought back tears as he implored lawmakers to “listen to the call” he and protesters were making for justice.

“Maybe by speaking with you today, I can make sure that his death will not be in vain.”

After the hearing, fist raised, he joined demonstrators on the streets outside the White House demanding justice and police reforms.

“There is systemic racism not just in our law enforcement but also in housing, education, and everything we do,” Democratic presidential candidate Joe Biden tweeted after the hearing.

“We have to do the hard work to end it.”
