United Nations, Jul 15 (AP) Mike Waltz, President Donald Trump's nominee for US ambassador to the United Nations, will face questioning from lawmakers Tuesday 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 militants in Yemen.

Waltz took responsibility even as criticism mounted against Defence 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.

Trump praised Waltz in the announcement, saying, “From his time in uniform on the battlefield, in Congress and, as my National Security Advisor, Mike Waltz has worked hard to put our Nation's Interests first.” The United Nations is facing major changes If confirmed, Waltz would be coming to the UN at a moment of great change. The world body is reeling from Trump's decision to slash foreign assistance — affecting its humanitarian aid agencies — and it anticipates US funding cuts to the UN annual budget.

Under an “America First” foreign policy realignment, the White House has asserted that "some of the UN's agencies and bodies have drifted” from their founding mission and “act contrary to the interests of the United States while attacking our allies and propagating anti-Semitism.” With America being the largest United Nations donor, cutting US funding to the UN budget would greatly impair operations.

Facing financial instability, the UN has spent months shedding jobs and consolidating projects while beginning to tackle long-delayed reforms. The UN is also facing growing frustration over what critics describe as a lack of efficiency and power in delivering on its mandate to end conflict and prevent wars.

John Bolton, a former US ambassador to the UN who was also national security adviser during Trump's first term, was critical of the current state of the UN.

“It's probably in the worst shape it's been in since it was founded,” Bolton, now an outspoken Trump critic, recently told The Associated Press.

Waltz has been meeting with senators Waltz spent the last several weeks meeting with Democrats and Republicans on the Foreign Affairs committee.

Democratic Sen. Tammy Duckworth said Monday that she and Waltz discussed a wide range of issues, including whether the Trump administration would use the UN to strengthen alliances and combat Chinese influence.

“I asked him questions about Signalgate,' but I also talked to him about how we are going to sway other nations within the United Nations to our side, in light of how much influence the PRC is having on other nations,” the Illinois senator said, using an acronym for the People's Republic of China.

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

“He'll be fine. Mike won't have any issues,” said Sen. Markwayne Mullin, R-Okla. “I mean, the Democrats are gonna do their thing. Whatever. Mike's used to taking incoming fire.” It is unclear how Waltz would approach the job. Trump's first nominee, Rep. Elise Stefanik, had built a track record in Congress of criticising the UN She vowed during her confirmation hearing in January to combat what she called antisemitism at the world body and lead a review of US funding.

She was expected to be confirmed, but Trump abruptly withdrew her nomination in March, citing risks to the GOP's historically slim House majority.

At the time, the loss of a mere handful of seats could have swung the House majority to Democrats and derailed their recently successful efforts to enact Trump's sweeping agenda.

Waltz is still on the White House payroll Waltz, whose Florida House seat was filled during a special election earlier this year, has spent the last few months on the White House payroll despite being removed as national security adviser. The latest list of White House salaries, current as of July 1, includes Waltz earning an annual salary of USD 195,200.

A White House official, granted anonymity to discuss personnel matters, said Waltz stayed on to “ensure a smooth and successful transition given the extreme importance of the role of NSA.” Waltz was the first Green Beret elected to the House and easily won reelection for a fourth term in November before Trump asked him to join the administration.
