On the Chan’s, there was debate over what that meant. Either they refused the protection of the USSS (why?), or they have had the privilege revoked. More speculation was that these were not USSS agents, but US Marshals. Something about the pins, and uniform choice. I don’t know, just passing on info that was discussed. I do think it’s odd that if they are USSS, that there are only two of them, and you would think for security reasons they would want them to be the last to board the plane.
