[...] The Obamas, who were not home at the time of the drowning, said in a statement last week that Campbell was a "beloved part of our family." "Today we join everyone who knew and loved Tafari — especially his wife Sherise and their twin boys, Xavier and Savin — in grieving the loss of a truly wonderful man," they said in a joint statement.
