Musk, the owner of car manufacturer Tesla and social media platform X, has been tapped by Trump to lead the proposed Department of Government Efficiency (DOGE), with biotech entrepreneur and former Republican presidential candidate Vivek Ramaswamy, after vocally supporting and financially backing his campaign for president.

After Musk helped tank a bipartisan bill to fund the government, Trump told conservative activists that he hadn't "ceded the presidency" to the tech billionaire.
