Before Tucker was executed, there were pleas for clemency from Waly Bacre Ndiaye, the United Nations commissioner on summary and arbitrary executions, the World Council of Churches, Pope John Paul II, and Italian Prime Minister Romano Prodi, among other world figures. Unusual pleas came from conservative American political figures such as Newt Gingrich and Pat Robertson, interceding on her behalf. Tucker did not ask for a pardon, only commutation of her death sentence to life in prison. Huntsville Prison's warden testified that she was a model prisoner and that, after 14 years on death row, she likely had been reformed. Despite these pleas, Bush signed her death warrant.
