Sen. Mitt Romney, R-Utah, joined demonstrators Sunday marching to the White House in protest of George Floyd's death in the custody of Minneapolis police.
About 1,000 protesters marched through Washington.
Asked why it was important for him to be present at the protest, Romney, who was wearing a face covering, said: "We need a voice against racism. We need many voices against racism and against brutality."
"We need to stand up and say black lives matter," added Romney, who was marching with a Christian group.
President Donald Trump has sharply and repeatedly criticized the demonstrations and called for state and local officials to crack down on them.
"No Americans should fear enmity and harm from those sworn to protect us," Romney tweeted last week. "The death of George Floyd must not be in vain: Our shock and outrage must grow into collective determination to extinguish forever such racist abuse."
