The ever-diminishing role of Marco Rubio – POLITICO

Ivo Daalder, a former U.S. ambassador to NATO, is a senior fellow at Harvard University’s Belfer Center and host of the weekly podcast “World Review with Ivo Daalder.” He writes POLITICO’s From Across the Pond column.

U.S. Secretary of State Marco Rubio traveled to Rome yesterday, looking to repair relations with both the Pope and the Italian government after their spats with President Donald Trump over the war in Iran.
