Survivors struggle to move forward after Buffalo mass shooting: "What are we going to do after this?"

Speaking to a grieving community Tuesday, an emotional President Biden condemned the racist ideology of the gunman who killed 10 black people at a Buffalo supermarket. 

"I call on all Americans to reject the lie and I condemn those who spread the lies for power, political gain and for profit," he said. 

The president was calling out those who have pushed the false, racist "replacement theory," the belief apparently shared by the accused shooter that white Americans are being systematically replaced by immigrants and minorities.
