Well, I guess you’re right, because he resigned a couple of days ago.

I’ve had the same issue, had to refresh every 10 seconds or so

Do you mean Verastigui? He’s a GOP staffer, for the record.

A fact check, as a counterpoint:

I’m confused then. It appeared the original post was stating that he did NOT receive a 21-gun salute, but rather a 3-gun salute. But there is evidence that he did, in fact, receive a 21-gun salute. That was my point.

From the research I have done, it also appears to be standard for some Marines to face the Presidential motorcade and for some to turn their backs (for security purposes). You can see a comparison online of the Biden vs. Trump inaugurations, and the military officers were in the same formation (some with backs turned) for Trump.

Re: your question, it looks like Biden did in fact receive a 21-gun salute...

DCA is less than two miles from the Pentagon, and they’re both on the Virginia side of the Potomac River. If you look on a map, you can see how close they are.
