John Kerry does. In the '04 campaign, he was on TV talking about various terror attacks and in his list he went through the embassies, the USS Cole, flight 800... the interviewer didn't make mention of it and nothing was ever said in other media about it(at least that I heard).
I listen to a lot of talk radio and someone put forth the notion that Kerry kept Gore out of '04 by threatening to tell what he knew about flight 800, but I don't remember who.
There are facilities in the White House, not the normal situation room, which everyone has seen in the past, has seen pictures of. There is a second situation room, behind the primary situation room, which has video conferencing capabilities. The director of the Pentagon, the defense chief, can speak from a national military command center at the Pentagon. The Secretary of State can speak from the State Department, the President from wherever he is, and they'll have this capability for video conferencing throughout this crisis.
In my time at the White House it was used in the aftermath of the Oklahoma City bombing, in the aftermath of the TWA Flight 800 bombing, and that would be the way they would stay in contact through the afternoon.
