John Oliver began Sunday's Last Week Tonight with an emotional monologue addressing the terrorist attack at Orlando gay club Pulse that left 50 people dead.

"It's still early and details are still emerging, and right now this just hurts," Oliver said. "And the worst thing is, this pain is so familiar."

"In Paris last November, terrorists seemed to target places symbolizing everything that is wonderful about France: culture, music, restaurants," Oliver continued. "In Orlando, early this morning, the gunman attacked a Latin night at a gay club in the theme park capital of the world. For the record, I will happily embrace a Latin night at a gay club in the theme park capital of the world as the ultimate symbol of what is truly wonderful about America."

But before Oliver returned to his regular show, he ended his message on a note of hope. "I'm sure there will be much more to say about Orlando going forward, but for right now, on a day when some dipsh-- terrorist wants us to focus on one man's act of brutality and hatred, it might be worth seeing this video, which was posted to Twitter today," Oliver said. "It shows hundred and hundreds of people today lining up around the block in Florida, waiting to donate blood. And it kind of reminds you that that terrorist dipsh-- is vastly outnumbered."
