In the wake of George Floyd’s death at the hands of Minneapolis police officers, Washington, D.C., has been a ground zero for rallies and protests against police brutality.

On Sunday, those rallies in the nation’s capital included Utah Sen. Mitt Romney.

In a tweet from Washington Post reporter Hannah Natanson, Romney is shown marching to the White House with what she estimated to be about 1,000 Christians. At the end of a 12-second video as part of the tweet, Romney says he is marching in order to “make sure that people understand that black lives matter.”

Since Floyd’s May 25 death in which now-former Minneapolis police officer Derek Chauvin put his knee on Floyd’s neck for nearly nine minutes, Romney has been outspoken on the subject.

In a May 30 tweet, Romney called Floyd’s murder “abhorrent,” while coming out in favor of peaceful protests. On Saturday, Romney tweeted a photo of his father, George Romney, taking part in a civil rights protest in the Detroit suburbs at some point in the late 1960s.

As Romney reached the White House with his fellow marchers, he was asked by an NBC reporter why it was important for him to be out here today.

“We need a voice against racism,” Romney responded. “We need many voices against racism and against brutality. We need to stand up and say that black lives matter.”
