Trump's comments came just before his departure on Air Force One, where he dismissed Musk's America Party attempt to shake up the Republican and Democratic landscape. "It's always been a two-party system," Trump said. Musk's announcement followed weeks of speculation, as he officially revealed the formation of the America Party on social media platform X.

Once strong collaborators, the alliance between Musk and Trump appears strained. The Tesla CEO previously supported the government efficiency initiative and had a role in a department designed to cut federal expenditure. However, their relationship soured following Musk's criticisms of Trump's recent tax and spending plan, which he deems restrictive, particularly regarding electric vehicles.

In a post on Truth Social, Trump commented on Musk's shift, stating: "I am saddened to watch Elon Musk go completely ‘off the rails’... becoming a train wreck." He voiced his opposition to Musk's aggressive push for an Electric Vehicle Mandate, which he accused of forcing adoption of electric cars too quickly.

Trump's legislative measures, enacted on July 4, eliminated incentives for electric vehicle purchases, asserting it allows consumers the freedom to choose between gasoline-powered cars, hybrids, or newer technology. His current spending bill also allocates funding for key areas such as border security and energy, while reducing budgetary support for healthcare and food programs.

Musk's proposed third party emerged amid public disagreements with Trump, further complicating their once-cooperative dynamic as both figureheads navigate their roles within an evolving political landscape.
