Medical magnate Peter Lamelas, nominated by Donald Trump to represent the United States in Argentina, is putting the final touches on his move to Buenos Aires, where he will take up the post as a political ambassador. Lamelas’ arrival comes at a time of unprecedented ideological alignment between Washington and Buenos Aires. The incoming envoy, a doctor and businessman, met President Milei previously at Mar-a-Lago, Trump’s residence in Palm Beach, where he is both a neighbour and a friend. The new ambassador will assume his role with a direct line to Trump and US Secretary of State Marco Rubio. He has a clear goal: to reinforce the alignment of the governments of Milei and Trump and deepen bilateral – and ideological – ties.
