It used to be that important deceased governmental figures, like Sen. Ted Kennedy, would "lie in state" while mourners paid their respects.
Apparently, the favored MSM term has become "lie in repose."
Interesting. Perhaps when you as a media outlet have to write to an audience's sub-high school reading level, you get your jollies by sounding swanky as often as possible.
Also, the Senator will be buried at Arlington National Cemetery to join some important neighbors who lie amongst our honored fallen: his brothers, of course . . . and my father.
