Donald Trump has announced seven new appointments for his incoming administration, recruiting Mike Huckabee as the US ambassador to Israel and Steven Witkoff as Middle East envoy.

Huckabee, the former governor of Arkansas, has a track record of hardline, occasionally provocative, pro-Israel rhetoric and previously said Israel has a rightful claim to the West Bank. In 2018, he said he dreamed of building a “holiday home” in the Israeli-occupied West Bank.

Trump said in a statement: “He loves Israel, and the people of Israel, and likewise, the people of Israel love him.”

Witkoff is a New York City-based real estate mogul, longtime friend of Trump’s and major campaign donor who testified as an expert witness for the defence in the New York attorney general’s case against the Trump family and its namesake business.

Trump’s first administration had an explicitly pro-Israel posture, relocating the US embassy from Tel Aviv to Jerusalem in a move decried by Palestinians as damaging to peace prospects.

Here’s what else happened on Tuesday:

Trump administration news and updates

• Elon Musk and Vivek Ramaswamy will lead a new Department of Government Efficiency, Trump announced. Despite the name, the organisation will not be a government agency. Trump said in a statement that Musk and Ramaswamy, a former Republican presidential candidate, will work from outside the government to “drive large scale structural reform, and create an entrepreneurial approach to government never seen before.”

• South Dakota governor Kristi Noem will lead the Department of Homeland Security. In the role, Noem would oversee everything from border protection and immigration to disaster response and the US Secret Service. She is a staunch Trump ally, once considered a contender to run with him for vice-president until her revelation that she shot and killed a “hated” dog on her family farm.

• Fox News host Pete Hegseth will serve as secretary of defence, Trump said. Hegseth, an army veteran and veterans advocate, has criticised so-called “woke” policies pursed by Pentagon leaders. He developed a friendship with the president-elect during his appearances on Fox & Friends.

• Two alumni of the first Trump administration will make a comeback, with former director of national intelligence and close Trump ally John Ratcliffe picked for CIA director, and William Joseph McGinley, who served as cabinet secretary in the first term, to serve as White House counsel.

US election news and updates

• The Republicans are just two seats shy of a 218 majority in the House of Representatives, after David Valadao won re-election in California’s 22nd congressional district and Gabe Evans defeated the Democratic incumbent Yadira Caraveo in Colorado’s 8th congressional district.

• Trump will meet congressional Republicans during his Biden White House visit on Wednesday as lawmakers prepare to “hit the ground running,” House speaker Mike Johnson said. Trump’s first years in office were marked by legislative chaos and “precious time was wasted”, Johnson told reporters on Tuesday. “We are not going to make those mistakes again.”

• Wisconsin Republican Eric Hovde has refused to concede to Democrat Tammy Baldwin in their US Senate race, saying he was “deeply concerned” about the election results but that seeking a recount was a “serious” decision and he was still reviewing his options, the Associated Press reported. Republicans have already won a majority in the Senate.

• The judge in Trump’s Manhattan criminal hush-money case has postponed deciding on whether to throw out the conviction on presidential immunity grounds. Judge Juan Merchan’s office told Trump’s legal team he would delay the ruling until 19 November after defence and prosecutors submitted letters asking for a postponement.

• Samuel Alito, a long-serving conservative justice on the supreme court, has no plans to step down, the Wall Street Journal reported. If he changes his mind, Trump and the Republican-controlled Senate could confirm a replacement and likely prolong the court’s conservative supermajority.

• Trump will reportedly oppose a US law that could lead to popular social media app TikTok being banned, despite bipartisan support for the measure.

• Trump advisers are reportedly mulling a “warrior board” to organise purge of top military officers. Donald Trump’s transition team is working on an executive order that would create a new body tasked with naming military leaders who should be demoted, the Wall Street Journal reported. The reported proposal is the latest sign that Trump may make due on his threat to retaliate against leaders at all levels of government who have broken with him, or who are perceived as disloyal.

• Trump’s latest cabinet appointments were revealed as Joe Biden’s administration appeared to continue to allow military aid to Israel after threatening sanctions if it did not act to counter the acute humanitarian crisis in Gaza by a 30-day deadline. State department spokesperson Vedant Patel said on Tuesday there was “no new policy or new assessment to offer but we’ll continue to have our conversations with the Israeli government”.
