President Joe Biden called Monday for action to end the type of “hate-fueled violence” that authorities said motivated a white man to fatally shoot three Black people at a Florida store over the weekend. Biden said people must speak out about injustice.

“We can’t let hate prevail, and it’s on the rise. It’s not diminishing,” Biden said at the White House as he met with civil rights advocates and the children of the Rev. Martin Luther King Jr. on the 60th anniversary of the March on Washington.

“Silence, I believe, we’ve all said many times, silence is complicity,” Biden said. “We’re not going to remain silent and, so, we have to act against this hate-fueled violence.”
