Mike Waltz, US President Donald Trump’s nominee for US ambassador to the United Nations, will face questioning from lawmakers today for the first time since he was ousted as national security adviser in the weeks after he mistakenly added a journalist to a private Signal chat used to discuss sensitive military plans.

The former Republican congressman is set to appear before the Senate Foreign Relations Committee for his confirmation hearing, with Trump looking to fill his remaining Cabinet position after months of delay, including the withdrawal of the previous nominee.

The hearing will provide senators with the first opportunity to grill Waltz over revelations in March that he added The Atlantic editor-in-chief Jeffrey Goldberg to a private text chain on an unclassified messaging app that was used to discuss planning for strikes on Houthi rebels in Yemen.

Waltz took responsibility even as criticism mounted against Defense Secretary Pete Hegseth, who shared the sensitive plans in the chat that included several other high-level national security officials. Hegseth shared the same information in another Signal chat that included family, but Trump has made clear Hegseth has his support.

Waltz was removed as national security adviser in May — replaced by Secretary of State Marco Rubio — and nominated for the UN role.

Even with Democratic opposition, Waltz only needs a majority in the 53-47 Senate, which Republicans control.
