PERSON: Mike Waltz

U.S. Mission to the United Nations (USUN)

Ambassador

Michael George Glen Waltz (born January 31, 1974) is an American politician, businessman, author, and former Army Special Forces officer who has served as the 32nd United States ambassador to the United Nations since September 2025 in the second Trump Administration. A member of the Republican Party, he previously served as the 29th national security advisor from January to May 2025 and was the U.S. representative for Florida’s 6th congressional district from 2019 to 2025. He was the first Army Special Forces soldier to be elected to Congress. Waltz received four Bronze Stars while serving in the Special Forces during multiple combat tours in Afghanistan, the Middle East, and Africa. He served in the Bush Administration as a defense policy director in the Pentagon and as counterterrorism advisor to Vice President Dick Cheney.

In 2018, Waltz was elected to the House of Representatives, defeating former ambassador Nancy Soderberg and succeeding Ron DeSantis, who was elected governor of Florida that same year. Waltz was re-elected in 2020, 2022, and 2024 with over 60% of the vote in each election. He was chair of the House Armed Services Subcommittee on Readiness for the 118th United States Congress. Waltz was considered one of Congress’s most hawkish members with regard to China, believing the Chinese Communist Party (CCP) is in a cold war with the U.S. and the West.

In 2021, Waltz was the first member of Congress to call for a full U.S. boycott of the 2022 Winter Olympics in Beijing over what he described as the CCP’s genocide and internment of Chinese Uyghur populations and the enslavement, forced labor, and internment camps of ethnic minorities in China. On November 12, 2024, President-Elect Trump announced he would appoint Waltz to serve as national security advisor in his second administration. Waltz resigned his House seat prior to taking office on January 20, 2025.

On May 1, 2025, it was reported that Waltz, along with Deputy National Security Advisor Alex Wong, would leave their posts following group chat leaks on the messaging platform Signal. Waltz served as NSA for 101 days, the second shortest tenure for a non-acting officeholder in the position (Mike Flynn, Trump’s initial first term NSA, lasted 24 days). The same day, Trump announced via social media that he intended to nominate Waltz to serve as Ambassador to the United Nations (replacing the withdrawn nomination of Elise Stefanik) and that Marco Rubio would take on an acting role as National Security Advisor.
