Apparently, Pres. Elect Trump thinks his children can. Just saw a couple of tweets which seem to indicate that he is seeking "Top Secret" security clearances for his children (I assume Don Jr, Eric & Ivanka).
Why he would do this truly escapes me, unless he plans to bring one or more of them onto the WH staff. I can't for the life of me figure what "need to know" any of them might have, otherwise. I thought he was going to leave them in charge of the Trump organization... No "need to know" there, I would think...
