And Corden said there's a huge reason why these shootings happen in the United States and not other developed countries, like his home of Britain.
"Last night was the biggest mass shooting in United States history," Corden said. "That's a record that's been set twice in just the two and a half years that I've been living in America."
Corden claimed that easy access to guns in the US sets the country apart from nations like Britain, where mass shootings are rare and do not occur as often as they do in the US.
"I come from a place where we don't have shootings at this frequency, so it's hard for me to fathom. But it should be hard for everyone to fathom," he said. "Gun violence should not be a staple of American life. Some say it's too early to talk about gun control. For those victims last night, it's far too late."
Corden mentioned a quote he saw by Robert Kennedy that stuck with him: "Tragedy is a tool for the living to gain wisdom, not a guide by which to live."
"Now is the time for gaining that wisdom," Corden said. "Somewhere, it has to stop. Maybe the time for the thoughts and prayers of congress members and the president have passed. We need to look to them to actually do something to prevent this from ever happening in the future."
