Richard Mills has officially ended his tenure as United States ambassador to Nigeria following a sweeping recall of US envoys ordered by Donald Trump.
The United States Mission in Nigeria confirmed on Tuesday that Mills’ last day in office was Friday, marking an abrupt end to a posting that began in May 2024. Ambassadorial roles are typically held for three to four years
Mills’ exit is part of a broader diplomatic reshuffle announced in December, which saw the recall of US ambassadors from more than two dozen countries, with African nations reportedly among the most affected.
His departure comes at a time of strained US–Nigeria relations, shaped by disagreements over visa policies and security concerns, even as both governments continued discussions aimed at strengthening bilateral cooperation.
US State Department officials clarified that the recalled ambassadors would retain their Foreign Service status and may return to Washington for reassignment if they choose.
Following Mills’ departure, the US Mission announced that Keith Heffern, the current Deputy Chief of Mission, has assumed duties as Charge d’Affaires pending further directives.
The development has sparked discussions over the future direction of US diplomatic engagement with Nigeria under the ongoing reshuffle.
