Watch LIVE: Congressional hearing on police reform proposals

WASHINGTON, DC -- In a dramatic moment in the crisis over race and policing, George Floyd's brother, Philonise Floyd, is among those testifying Wednesday before the U.S. House Judiciary Committee on reform proposals, following his death in the custody of Minneapolis officers that triggered national outrage.

Asked what he plans to tell the committee as he arrived on Capitol Hill, Floyd said, "Justice for George."

Also testifying are Floyd family's lawyer, Benjamin Crump, a former Secret Service agent and the sister of a federal law enforcement officer killed in the line of duty.

The hearing will "examine the crisis of racial profiling, police brutality and lost trust between police departments and the communities they serve," the panel said.
