That's what Kellyanne Conway (?) has said.

"Mr Trump is the President,
so everything he does is 'Presidential".

(Mr Trump took a 'Presidential' dump this morning)

could you please nuke those North Koreans. Drop a big one for me. You know what I told him? Do you know? You know, I told him, we will think about it. I'm very serious. We will do very serious things. We're serious people. We do serious things, seriously. So North Korea is on watch. It's not just me that's watching. It's Elvis. He's watching too. Great call. Love calls.

I'm the President, right? So that makes everything I do ok, right. I mean, why do we have nuclear weapons if we can't use them? They're pretty when they explode. I like fireworks! Even if they're used, the planet has legitimate ways to try and get rid of the radiation, to shut the whole thing down. Where's Nikki? I told her to bring me my Tonka over half an hour ago!"
