Biden spoke on the recent mass shooting in Buffalo, where 10 Black people were killed including a retired police officer working as a security guard at the store.

“When I think of Aaron [Salter] … I think of all of you,” he said. “Being a police officer isn’t just what you do, it’s who you are, and it’s never easy.”

Biden highlighted his efforts to curb gun violence in recent years, pointing out that “being a cop today is a hell of a lot harder than it’s ever been” in part because they have to face “weapons of war” out on the streets.

“I believe in the 2nd Amendment, but it’s not a right that’s absolute,” he said.

Biden spoke virtually because he’s recovering from COVID-19 after testing positive Thursday morning.

On Sunday, the president’s physician Dr. Kevin O’Connor said Biden’s symptoms continued to “improve significantly.”
