Seems to me, the VISAs have been suspended, so they are not currently valid. Anyway, detained is not good enough, expelling them is.
Oh, no! One has been held 14 hours!!! The hugh manatee! Did CNN bother asking if the next flight back to where he came from was 14 hours or was the lawyer the one detaining him here? Vet them thoroughly and ship them back from where they came.
Why were they trying to slip in under the wire?
