The owner of the US group chat leak group officially begins to perform his duties at the United Nations

On September 21, the new US Permanent Representative to the United Nations, Michael Waltz, handed over his credentials to UN Secretary-General Guterres at the UN headquarters in New York and officially began his duties. Waltz, 51, is Trump's first national security aide since he became the US president for the second time in January this year, and has been controversial due to his involvement in the "group chat leak" incident in March this year. Trump announced on social media on May 1 that Waltz was nominated as the US Permanent Representative to the United Nations, and the national security aide position was represented by Secretary of State Rubio. On September 19 local time, the US Senate voted to confirm Waltz as the US Permanent Representative to the United Nations. During his Senate nomination hearing earlier this year, Mr. Waltz stressed that the Trump administration's "priorities" for UN policy included pushing for UN reform, reviewing UN funding and rooting out so-called "anti-Semitism" within UN agencies.
