She wouldn't tell him who was coming but, she would tell him that more important business came up then a silly parade. Given that it is an ISB agent and they're usually hush hush she would not really tell anyone that didn't need to know. Conversely, since Tucker is a captain she would be leaving him in charge of the perimeter defenses with the other lieutenants to lord over. Remember that only extrenious circumstances will outside guards be allowed into the palace so Vale will expect Tucker to do a bang up job making sure that dosen't happen.

So Tucker will have known to the extent of letting the shuttle land and not shooting Loretta, basically [@agentmanatee] :P
