Since Obama nominated Susan Rice for the position of National Security Adviser, questions have been asked in the Nigerian media about allegations of her role in the death of the winner of Nigeria's annulled 1993 presidential election, Chief MKO Abiola.

Following an interview with the Nigerian Punch in which Dr. Ore Falomo, Chief MKO Abiola's personal physician, accused the CIA of involvement in the death of Chief MKO Abiola, a former Nigerian Minister of Aviation, Chief Femi Fani-Kayode, in an opinion piece published also in the Nigerian Punch, revisited the question that has been the subject of speculations alleging CIA involvement in the death of the Nigerian multimillionaire politician; and allegations that Rice might have, knowingly or unknowingly, played the role of messenger of death in the case.
Rice was one of the last persons who saw Abiola alive and reportedly served him his last cup of tea. Abiola died of cardiac arrest within an hour of drinking the tea.
