## Recent Political Involvement
In January 2025, Musk was appointed to head the Department of Government Efficiency (DOGE) in the Trump administration[3][5]. During his tenure, DOGE implemented significant cuts across federal departments, resulting in 250,000 workers being fired or bought out, including reductions at environmental agencies like the EPA and NOAA[3].
Musk was a substantial financial supporter of President Trump’s election campaign, contributing $288 million to elect Trump and his allies[3]. Initially, the relationship between Trump and Musk appeared strong, with Trump calling him “a truly incredible guy” and Musk referring to himself as “first buddy”[3].
However, Musk has recently indicated a shift away from government work, stating that his focus will return to running his business ventures[3]. When asked about the connection between his various businesses, Musk described them as “things that improve the probable trajectory of civilization,” with goals such as making life multi-planetary and ensuring “the long-term survival of life and consciousness as we know it”[3].
As of May 2025, Forbes estimates Musk’s net worth at US$424.7 billion, making him the wealthiest person in the world, a position he has held since 2021[5].
