On February 25, 2016, he was nominated as the interim prime minister of Haiti. On March 20, 2016, the lower house of the chamber of deputies of Haiti's parliament rejected the general policy of Jean. He did not receive the confidence vote by the majority of deputies. The next day,
Enex Jean-Charles was chosen to replace Jean as the new prime minister of Haiti. The Transitional Presidential Council, formed in 2024 after the resignation of acting Prime Minister
Ariel Henry and the escalation of the
gang war in Haiti, chose Jean as its head on March 7, 2025. The goal of the council is to organize elections to take place before February 2026. == United States Sanctions ==
