Overview

  • On July 15, Waltz appeared before the Senate Foreign Relations Committee for his confirmation hearing as U.S. ambassador to the United Nations.
  • He insisted no classified information was shared in the Signal chat and accepted responsibility for adding a journalist to a discussion of Yemen strike plans.
  • Democratic senators including Chris Coons, Tim Kaine and Cory Booker pressed him on his judgment and on U.S. messaging protocols as two Pentagon investigations proceed.
  • With a 53-47 Republican Senate majority requiring only 50 votes for approval, Waltz’s nomination is widely expected to succeed despite Democratic opposition.
  • If confirmed, he would become the final member of President Trump’s Cabinet and lead U.S. representation at a United Nations coping with budget cuts and calls for reform.
