The day of the explosion the “person of interest” was questioned by police. This person was mentioned on all of the news outlets. Two days later none of the media outlets carried that this person was going to be deported due to national security concerns immediately after both John Kerry and the president met with the foreign minister of Saudi Arabia. The following day Janet Napolitano was questioned about this person but gave no information. Yes Glenn Beck has been talking about it.
So your implication is that since nobody else in the media has talked about it then it is of no significance.
