Philonise, who was introduced by Washington, D.C., Mayor Muriel Bowser, addressed the nation from his home in Texas early in the virtual convention.
"My brother George was selfless. He always made sacrifices for his family, friends and even complete stragners. George had a giving spirt -- a spirit that has shown up on streets around our nation and around the world," Philonise shared. "People of all races, all ages, all genders, all backgrounds, peacefully protesting in the name of love and unity."
"It's a fitting legacy for our brother, but George should be alive today," he continued, before naming many other Black men and women who have been killed in recent years in acts of hate.
"It's up to us to carry on the fight for justice. Our actions will be their legacies," Philonise continued, before asking everyone to join him in a moment of silence to honor his brother and the hundreds of others who have lost their lives to racial injustice.
