The Greek triple jumper expelled from the Olympics for sending a racist tweet about African immigrants and the West Nile virus is speaking out against the decision to ban her from competition in London.

Voula Papachristou was left in Athens by the Hellenic Olympic Committee after sending a tweet that read, “with so many Africans in Greece at least the West Nile mosquitos will eat homemade food.” Her comment generated a minor uproar in Greece, then became an international story when Greek officials decided to kick her off the Olympic team.
