Mike Waltz, President Donald Trump’s nominee for U.S. ambassador to the United Nations, appeared before the Senate Foreign Relations Committee on Tuesday for his confirmation hearing.

Waltz, who was forced out as National Security Adviser over the incident, claimed that “no classified information” was divulged on the chat even though Defense Secretary Pete Hegseth disclosed key details of the military strike in real time to the group, which included Atlantic Editor Jeffrey Goldberg.
