President-elect Donald J. Trump is assembling the cast of characters who will serve in his cabinet and in other senior positions during his second term. The cabinet always comprises at least 16 positions — the vice president and the heads of the 15 executive departments — and presidents have discretion to elevate other officials, like the White House chief of staff, to the cabinet level. This page will be updated as new announcements are made.

President-elect Donald Trump has tapped Fox News personality Pete Hegseth to lead the Department of Defense, making him the first on-air talent from the conservative-leaning network to join the incoming administration. And he may not be the last.

Hegseth, a decorated combat veteran who served in Iraq and Afghanistan, will leave the network immediately, a Fox News representative said Tuesday.

Hegseth, 44, has been a co-host of the weekend edition of morning program “Fox & Friends” since 2017 alongside Will Cain and Rachel Campos-Duffy. An Army National Guard officer, he joined the network as a contributor in 2014.

“Pete is tough, smart and a true believer in America First,” Trump said in his statement announcing the appointment. “With Pete at the helm, America’s enemies are on notice — Our Military will be Great Again, and America will Never Back Down.”

A number of Fox News contributors are expected to join the new Trump administration. Former Immigration and Customs Enforcement Director Tom Homan, who made paid appearances on the network, was named as Trump’s border czar on Monday.

But Hegseth’s exit is a surprise. He is a full-time host who enjoys a comfortable salary and the perks that come along with a high-profile TV job.

There has been chatter inside the network that others may follow him.

The revolving door of White House administrations and cable news channels has been active in recent years due to the number of opinion programs the outlets now present.

Former White House Press Secretary Kayleigh McEnany joined Fox News in 2021 after Trump lost the 2020 election.

Jen Psaki, who served in the same capacity for President Biden, moved to MSNBC after serving two years. She now hosts a program on Sundays and Mondays on the network. Symone Sanders, former chief spokeswoman for Vice President Kamala Harris and former Biden campaign senior adviser, is also a weekend host on the network.

Hegseth is a graduate of Princeton University, and has a graduate degree from Harvard University. For his military service, he was decorated with two Bronze Stars, as well as a Combat Infantryman Badge.

Hegseth is a best selling author for Fox News Books, the network’s publishing imprint.

The Biden administration will support a U.N. treaty this week that will create a new cybercrime convention that includes China and Russia — which has not sat well with some lawmakers and critics. 

Since 2001, the global governance around cybercrime has largely been coordinated by the Budapest Convention, a product of the Council of Europe that includes 76 countries. It does not include Russia or China. However, under the U.N.’s new cybercrime convention, these two adversarial nations will be welcomed into the global cybercrime governance fold.  

The move, confirmed by top officials familiar with the issue, has been met with concern from those who fear that a new global alliance on cybersecurity involving two of the nation’s most adversarial nations could spell trouble.

“We recognize that defending human rights and core principles of internet freedom is not easy,” a group of Democratic lawmakers on the Hill wrote last week to top officials in the Biden administration, including Secretary of State Antony Blinken, Attorney General Merrick Garland and Assistant to the President for National Security Affairs, Jake Sullivan. “Russia, China and other regimes opposed to democratic freedoms are always working to create international legitimacy for their actions and worldview … Unfortunately, these efforts – while laudable – are insufficient to fix fundamental flaws in the convention.”

The decision to support the new treaty came after months of deliberations between the Biden administration and others, including hundreds of nongovernmental entities involved in human rights and other relevant issues. According to a senior administration official, the U.S. “decided to remain with consensus,” arguing the U.S.’s sway on global “rights-respecting” cybersecurity policy will be greater under the new convention.

To help address concerns that have been raised about the convention, the Biden administration plans to develop a risk management plan and will engage with nongovernmental stakeholders to help refine it. 

A “consensus proceeding” took place Monday, and the resolution was approved without a vote. According to Politico, it is expected to be adopted by the General Assembly later this year.

Meanwhile, President-elect Donald Trump announced on Monday that he would be nominating New York GOP Rep. Elise Stefanik to be the next U.N. ambassador in his administration.

The White House declined to comment on the record for this story.
