Gutiérrez rose steadily through the army ranks and in 1990–92 served with the United Nations observer mission to Nicaragua. As a young man, he demonstrated little interest in politics, but during the 1990s he sympathized with fellow Ecuadorans as they became increasingly disenchanted with corruption and poverty. In 1997, as aide-de-camp to Pres. Abdalá Bucaram Ortiz, he refused an order to use force against a crowd outside the presidential palace. Bucaram fled the palace and was later removed from office by the National Congress. In 1999 Gutiérrez repeatedly questioned the government's conduct and pointedly refused to shake Pres. Jamil Mahuad Witt's hand during a public ceremony in December.
