Tonight Show host Jimmy Fallon led off Monday night’s show by addressing the events in Charlottesville over the weekend and paying tribute to car-ramming victim Heather Heyer.

Said Fallon: “What happened over the weekend in Charlottesville, Virginia, was just disgusting. I was watching the news like everyone else, and you’re seeing Nazi flags and torches and white supremacists, and I was sick to my stomach.”

Fallon discussed his children and how hard it would be to explain the situation to them:

“They’re two-years-old and four-years-old. They don’t know what hate is. They go to the playground and they have friends of all races and backgrounds. They just play, and they laugh, and they have fun. But as kids grow up, they need people to look up to, to show them what’s right, and good. They need parents and teachers, and they need leaders who appeal to the best in us.”

He also blasted Trump:

“The fact that it took the president two days to come out and clearly denounce racists and white supremacists is shameful. And I think he finally spoke out because people everywhere stood up and said something. It’s important for everyone — especially white people — in this country to speak out against this. Ignoring it is just as bad as supporting it.”

Adding:

“We all need to stand against what is wrong, acknowledge that racism exists, and stand up for all that is right, and civil, and kind…And to show the next generation that we haven’t forgot how hard people have fought for human rights. We cannot do this. We can’t go back. We can’t go back.”
