The Senate on Monday confirmed Mike Waltz, President Donald Trump’s ambassador to the United Nations, to also serve as the United States representative to the U.N. General Assembly.

Waltz, formerly President Donald Trump’s national security adviser, was confirmed in a 54-45 vote. Three Democrats, Sens. John Fetterman (D-PA), Mark Kelly (D-AZ), and Jeanne Shaheen (D-NH), joined most Republicans in supporting his nomination, while Sen. Rand Paul (R-KY) was the only Republican to vote no.
