henry, to rlace him. he was supposed to be sworn in today. for more on the assassintation of president moise, and the shockwave it's sent through haiti, i'm joined by robert fatton. he's a professor of government and foreign affairs at the university of virginia. he has written widely on haiti through the years. he joins me from charlottesville. professor fatton, thank you so much for being here. haiti has really been in a constitutional crisis for several months, now, people on the ground say it's hit a new rock bottom. but talk about the gravity of the last 24 hours and the difference now that the president has been murdered. >> well, this is a shocking event in the history of haiti. the last assassination of a president was 1915, so this is not the usual pattern at all. we've had coups, we've had attempted coups, we've had, obviously, very nasty dictators who killed a lot of people, but that, especially given that it was, as far as we know, an armed attack by foreign mercenaries, it's really a different pattern, and it's difcult to understand why that would have happened and who would benefit from it. it is really something that is out of the ordinary.
