(NewsNation) — Donald Trump’s proposed advisers for his second presidential administration comprises politicians, a TV news host, tech entrepreneurs – and billionaires.

A billionaire himself, Trump is the richest American president in history, accounting for inflation, with a $5.2 billion estimated net worth as of Nov. 15, which is down from $6.7 billion on Oct. 31.

His proposed Department of Government Efficiency would be led by billionaire friend Elon Musk and entrepreneur Vivek Ramaswamy.

Trump’s Cabinet during his first term was considered to be the wealthiest Cabinet in previous administrations. While the DOGE position is not technically a Cabinet post, Trump’s picks so far include plenty of wealthy individuals.

But first, the president-elect needs the Senate to confirm his appointments, or he needs to arrange to install them via a temporary process known as recess appointments.

Here is the net worth of the wealthiest members of Trump’s proposed second-term administration.

The Billionaires

Elon Musk’s net worth

Elon Musk, owner of SpaceX, X (formerly Twitter) and Tesla, is the world’s richest man, far surpassing his new boss in personal wealth.

According to Forbes’ real-time billionaires list, as of Nov. 15, Musk has a net worth of $298.4 billion, owing to his tech companies.

The X owner first appeared on Forbes’ billionaire list in 2012 with a net worth of $2 billion.

Forbes reported that his net worth in October 2011 was $680 million.

Formerly a Trump rival, Ramaswamy entered his name into the hat for Republican presidential nominee in 2023 but dropped out at the beginning of 2024. He endorsed Trump and became a political surrogate for him throughout the election cycle.

Ramaswamy, a Harvard graduate, earned his fortune through his pharmaceutical company Riovant Sciences, from which he stepped down as CEO in 2021.

The entrepreneur’s net worth is $1 billion, according to Forbes as of Nov. 15. He was named to Forbes’ America’s Richest Entrepreneurs Under 40 list in 2016.

The Millionaires

Vice President-elect JD Vance, a U.S. senator from Ohio, has an estimated net worth of about $5 million to $10 million. As vice president, Vance will earn $235,000 per year.

The Yale Law graduate completed law school without debt because of his time in the Marine Corps. He earned money through high-paying jobs at elite law firms and then released a book “Hillbilly Elegy” in 2016. Netflix later distributed a movie version.

Robert F. Kennedy Jr.’s net worth

He shares the prosperous Kennedy name, and Robert F. Kennedy Jr.’s net worth is around $15 million,  Forbes estimates.

RFK Jr. ran an unsuccessful presidential campaign on the independent ticket but withdrew from the 2024 race in August. He endorsed Trump and was later named to Trump’s Cabinet on Thursday.

Trump’s picked him to lead the Department of Health and Human Services.

South Dakota Gov. Kristi Noem was tapped to serve as the Department of Homeland Security secretary under the Trump administration.

Before becoming governor, Noem was the South Dakota’s congressperson from 2011 to 2019.

OpenSecrets.org, a research group that tracks money in U.S. politics, reports Noem’s net worth was $2.3 million in 2017, the last year of published reports on her finances.

That number has likely changed since then.

Marco Rubio’s net worth

Sen. Marco Rubio, R-Fla., will serve as the president’s top diplomat as secretary of state if his nomination holds.

His net worth was $1.2 million in 2018, according to OpenSecrets.org’s most recent report. That figure has likely changed since then.

Rubio has served as the senior U.S. senator for Florida since 2011. Before that, he was speaker of the Florida House of Representatives from 2006 to 2008.

Despite a rivalry with Trump during the 2016 GOP primaries, Rubio has been a steadfast Trump supporter since the president-elect’s first term.
