Jimmy Kimmel has already said what he needs to say about the events in Las Vegas.

But on Tuesday night, Kimmel dedicated a small part of his opening monologue to take aim the "nuts" who spent time criticising him and others for wanting to do something about gun control, following what happened on Sunday.

He got straight to the point.

"They say it's inappropriate to be talking about it, because it's too soon. Well, maybe it's too soon for you, because maybe deep down inside your heart you know you bear some responsibility for the fact almost anyone can get any weapon they want," he said.

"Now you want to cover yourself until the storm of outrage passes, so you can go back to your dirty business as usual. It's not too soon for us, because we're Americans, and last time I checked the first amendment is as important as the second amendment.

"So we will talk about it, and shame on you for suggesting otherwise." And with that, Kimmel returned to the show, riffing about none other than Trump's visit to Puerto Rico.
