The point is that Barry0 did NOT know what was going on. He was yanked back from the golf course after the mission was already underway.
Here’s a picture of him coming back from golfing. He has the same clothes on, apparently went straight to the Situation Room.

Is it me or is he running rather than walking in that picture? Seems a bit of a deep step for an ordinary walking gate. He’s in a hurry. Something unexpected he’s responding to.
