The Senate confirmed former National Security Advisor Mike Waltz on Friday to be U.S. ambassador to the United Nations, capping off a monthslong confirmation process that was marred by delays just days before the start of the U.N. General Assembly next week. 

Waltz, a former congressman from Florida and a Green Beret, was confirmed by a 47-43 vote in the Senate on Friday afternoon, with three Democrats and one Republican crossing party lines. Sens. Jeanne Shaheen (D-NH), the ranking Democrat on the Senate Foreign Relations Committee, John Fetterman (D-PA) and Mark Kelly (D-AZ) voted in favor of Waltz’s nomination, while Sen. Rand Paul (R-KY) was the only Republican to oppose. 

Waltz’s journey to his current role began when President Donald Trump removed him from his post as White House national security advisor in late April and selected him to replace Rep. Elise Stefanik (R-NY) as his pick for U.N. ambassador. The White House pulled Stefanik’s nomination in late March, more than two months after the Senate Foreign Relations Committee had advanced her nomination, amid concerns that her absence in the House could hurt Republicans’ ability to govern with their slim majority.

The former national security advisor was facing heavy scrutiny at the time over the Signal chat incident in which Waltz inadvertently added Atlantic Editor-in-Chief Jeffrey Goldberg to a group chat of top national security officials discussing imminent strikes on the Houthis on the non-secure messaging app. Prior to the “Signalgate” incident, Waltz had already been viewed as a vulnerable target for ideological rivals and personal foes in the administration because of his hawkish approach on foreign policy. 

While Trump initially stood by Waltz, he eventually relented and in early May announced his intention to move the former congressman to the U.N. post. Waltz had already faced a setback after Trump fired six National Security Council officials whose views were aligned with Waltz. Their ouster was driven by an intervention by far-right activist Laura Loomer. 

Waltz, a staunch supporter of Israel and an outspoken critic of Iran, faced delays of his own during his Senate confirmation process this summer, with Paul siding with all Democrats on the Foreign Relations Committee to block his nomination from advancing to the full Senate over concerns with Waltz’s national security and foreign policy positions. 

Shaheen eventually broke the stalemate in July, voting for Waltz because of his public and private support for continued U.S. global engagement than other figures in the administration, as well as potential alternatives Trump could nominate. 

Multiple outlets reported at the time that Shaheen, who is retiring next year, conditioned her support for Waltz on the Trump administration committing to providing $75 million in aid to Haiti and Nigeria, which had just been approved. Sen. Jim Risch (R-ID), the chairman of the committee, told Jewish Insider that the aid package was not directly tied to Shaheen’s support for Waltz.

During his confirmation hearing that month, Waltz said he would serve as a blockade to “anti-Israel resolutions” in the U.N. General Assembly and vowed to push for the dismantlement of the United Nations Relief and Works Agency over some of its employees’ involvement in the Oct. 7, 2023, Hamas attacks. He also said he supported U.S. sanctions against Francesca Albanese, the U.N. special rapporteur for Israel and the Palestinian territories, amid widespread accusations she has espoused antisemitic rhetoric in her commentary on Israel.

Waltz will take over for Dorothy Shea, the career diplomat who filled the role in an acting capacity as chargé d’affaires during the nine-month vacancy. His first full week on the job will coincide with the General Assembly, bringing world leaders together in New York City for high-level discussions on issues ranging from Russia’s war in Ukraine to European countries’ push for Palestinian statehood.

Several major Jewish organizations are expected to call on the Senate to “swiftly” confirm President Donald Trump’s nominees for special envoy to monitor and combat antisemitism and international religious freedom ambassador. 

The groups, led by the Jewish Federations of North America, are writing in a letter to Senate Majority Leader John Thune (R-SD) and Senate Minority Leader Chuck Schumer (D-NY) that filling the roles is “of utmost importance in fighting growing antisemitism and ensuring freedom of religion or belief worldwide,” according to a draft obtained by Jewish Insider. The letter is set to be sent on Tuesday, according to a source with knowledge of the draft.

“We dare not delay in filling these critical positions that protect human rights around the world,” the letter states. “To that end we strongly urge you to prioritize filling these positions, sending a powerful signal to governments around the world that the United States upholds our constitutionally guaranteed rights to life and liberty, to freedom of religion and belief, and calls on them to do the same.”

In April, Trump tapped Rabbi Yehuda Kaploun, an Orthodox businessman and Chabad rabbi who served as a campaign surrogate, to serve as the next U.S. special envoy to monitor and combat antisemitism. In the Biden administration, that role was filled by Deborah Lipstadt, a Holocaust historian at Emory University. In May, the two authored a joint op-ed, with former antisemitism envoy Elan Carr, calling for action after two Israeli Embassy staffers were killed outside the Capital Jewish Museum in Washington. 

Trump named former Rep. Mark Walker (R-NC) as the U.S. ambassador-at-large for international religious freedom. Both positions require Senate confirmation, and neither has had a confirmation hearing yet. 

“We believe that these ambassador-at-large positions are crucial to protecting vital human rights, promoting religious freedom and vigorously confronting the global surge in antisemitism,” the Jewish organizations wrote. 

JFNA CEO Eric Fingerhut told JI on Tuesday that the positions must be filled to help Jewish organizations combat rising antisemitism.

“The 141 Jewish Federations across our system are on the front lines of responding to and combatting antisemitism, and every single day we hear from them about the elevated levels of antisemitism our communities are facing,” Fingerhut said. “The government is a critical partner in our fight against antisemitism, both at home and around the world, so we must make sure that these roles do not remain vacant.”

A spokesperson for Thune did not respond to a request for comment. 

A spokesperson for Schumer referred to the hold the Senate minority leader currently has on dozens of Trump nominees, and Trump’s recent message to Schumer to “go to hell” after bipartisan negotiations broke down. The spokesperson declined to comment specifically on Kaploun or Walker. 

“President Trump has focused on promoting religious freedom and fighting antisemitism in a historic way,” White House deputy press secretary Anna Kelly told JI in a statement. “He wants all of his nominees confirmed as quickly as possible, including Yehuda Kaploun and Mark Walker, whose roles will be critically important to protecting Americans of faith.”

Current signatories to the letter include the Conference of Presidents of Major American Jewish Organizations, the Anti-Defamation League, the Orthodox Union, the Israeli-American Council, the Zionist Organization of America, Hadassah, American Jewish Committee, Agudath Israel, B’nai Brith International, the Louis D. Brandeis Center for Human Rights Under Law, NORPAC, Combat Antisemitism Movement, Religious Zionists of America and the American Association of Jewish Lawyers and Jurists.

Vice Admiral Brad Cooper, the deputy commander of U.S. Central Command who is nominated to be the next CENTCOM head, said at his Senate confirmation hearing on Tuesday that the United States is prepared for the possibility that Iran will attempt to place mines in the Strait of Hormuz to close off the strategic waterway.

The Iranian parliament approved a move earlier this week to close the strait, but that decision would be dependent on the approval of the Iranian leadership, and it’s not clear whether the ceasefire between Israel and Iran might hold off such a move. Around a third of the world’s oil supply passes through the strait, which connects the Persian Gulf and several Gulf states to the Arabian Sea.

The incoming CENTCOM leader, who previously led naval forces in CENTCOM and the Fifth Fleet based out of Bahrain, told the Senate Armed Services Committee that the U.S. “has sufficient capacity and capability to handle the threat” of mining the Strait of Hormuz, and that it is keeping a close eye on Iranian movements that would signal such an operation is occurring.

“It would certainly be important for us to watch what they’re doing and attempt to both anticipate and then react faster than the threat,” Cooper said. “It’s a significant threat. It’s a known threat, and one that we’re watching.”

Cooper acknowledged that the potential shutdown of the Strait of Hormuz would have “significant” impacts on U.S. operations in the Middle East. He said it would be a “complex problem,” given that Iran has stockpiles of thousands of mines, and noted that “historically in mine warfare, nothing happens quickly,” saying the operation would be a matter of “weeks and months, not days.”

Cooper said that U.S. and Israeli strikes, and particularly Israel’s successes against Iran and its proxies, have weakened and degraded Iran significantly, but added that Iran remains the primary destabilizing agent in the region and a sponsor of global terrorism.

“They possess considerable tactical capability, one element of which we saw yesterday,” Cooper said, referring to Iranian missile barrages at U.S. bases in Qatar and Iraq. “We’ve got to be in a three point stance, ready to go every single day. “

Pressed repeatedly by Democrats on whether the U.S. is planning for a ground invasion or for regime change in Iran, Cooper declined to discuss specifics in public, stating that his role is and would be to provide options to the administration’s civilian leadership and to prepare for various potential scenarios.

Cooper added that “deterring Iran and its proxies … is a critical element of our national security,” noting as well that some of the Iranian-aligned militia groups in the region, as well as the Houthis, remain an active threat. He highlighted that Iranian proxies have attacked Americans around 500 times in the past 20 months.

Lt. Gen. Alexus Grynkewich, the director of operations for the Joint Chiefs of Staff and former director of operations for CENTCOM, who was testifying alongside Cooper, said that “the Houthis are likely to be a persistent problem that we’ll be dealing with in the future a few times again.”

Cooper said it might take several months for normal commercial trade to resume through the Bab-el-Mandeb Strait after the U.S.-Houthi ceasefire agreement was reached last month.

Cooper said that the U.S. is prepared for a range of scenarios should the Houthis break the ceasefire. He also warned that the Yemeni terrorist group is “extremely well supplied by the Iranians” and is increasingly entrenching underground.

He added that, learning from Hamas, Iran and other groups in the region, U.S. adversaries entrenching underground is likely to be a growing problem in the future. He highlighted the work of Israel and U.S.-Israeli collaborative efforts to counter this threat.

Cooper emphasized concerns about the growing cooperation between U.S. adversaries such a Iran, China, Russia and North Korea. He expressed particular frustration about the flow, through Iran, of weapons components from China to the Houthis, and China’s longstanding failure to take action against the Houthis.

The vice admiral emphasized that the U.S.’ efforts in Syria going forward will be led by diplomacy and appear to be headed in a positive direction, but added that the U.S. must remain vigilant and active to focus on the ongoing threat from ISIS.

“Stability in Syria can translate into security in the United States,” Cooper said. “And here’s how those dots connect. ISIS thrives in chaos. If the government of Syria, now seven months into their existence, can help suppress that ISIS threat, along with the U.S. forces in the region, that stability helps create our own security. I’m optimistic for the future.”

He argued that now is not the time for the U.S. to be pulling back from the Middle East, and that any drawdown of troops from Syria — which the Trump administration has pursued — should be based on conditions on the ground, emphasizing that the U.S. remains the leader of the international coalition to combat ISIS.

Cooper said that the Abraham Accords and Israel’s incorporation into Central Command “presents extraordinary opportunities to advance security and enhance deterrence” in the region, and that he would continue to work on those relationships — a priority for the outgoing CENTCOM leader, Gen. Erik Kurilla.
