(GRN)Greece's triple-jump champion was expelled from the Olympics after posting a tasteless tweet about Africans and the West Nile virus. Hellenic Olympic Committee officials announced Voula Papachristou wouldn't travel to London after she tweeted a joke about African immigrants. On Monday, the track athlete posted a tweet reading, "with so many Africans in Greece, at least the West Nile mosquitos will be eating food from their own home." The comments created an uproar on Greek social media. Papachristou didn't address the criticism on Twitter for two days. Greece later announced it would place Papchristou "outside the Olympic team for statements contrary to the values and ideas of the Olympic movement."
