Why did Biden say 'salute the marines' out loud and kept walking without saluting marines?

@Mike: "Civilians don't give military salutes." OK, but I bet the Commander-in-Chief does?

He forgot where he was. Kamala doesn't salute either. She thinks she's queen sheba

Probably for the same reason he said "And by the way you know why I sit on the stand and it get hot .... I got a lot of ... uh ... harry legs that turn that that that that um turn blonde in the sun... and the kids used to come up and reach in the pool and rub-rub my legs down so it was straight... and then they watched the hair come back up again and I looked at em. So I learned about roaches and kids jumpin on my lap... and I love kids jumpin on my lap! "

In other words, he's an idiot.

Because he had an earpiece on and he was repeating what the person said on his earpiece. He wasn't able to connect it to the suggested expected behavior. It's a sign of his cognitive dissonance. 

Civilians don't give military salutes.

@graphic: aside from Reagan and Trump. which presidents gave military salutes?

And Presidents wear civilian clothes.
