After the "Group Chat Gate" leak incident, amidst doubts and opposition from various sectors, U.S. President Trump and White House officials have repeatedly supported National Security Advisor Michael Waltz. However, on May 1, Trump announced on social media that Waltz was nominated as the U.S. Permanent Representative to the United Nations.
After the news broke, former Democratic vice-presidential candidate and Governor of Minnesota, Waltz, joked on social media: "Waltz has left the group chat."
Why was Waltz ultimately dismissed more than a month after the "Group Chat Gate" incident? What are the evaluations from various sectors? What further impacts will arise?
