What the Evidence Shows
The claim states that Elon Musk said President Donald Trump will bankrupt the country. The search results and structured sources do not contain any direct quotes or credible reports of Elon Musk making this specific statement. Instead, one source mentions Elon Musk criticizing Congress for making America bankrupt and blasting a 'disgusting' Trump bill, but this criticism is directed at Congress and a bill associated with Trump, not a direct statement that Trump himself will bankrupt the country.
Other sources focus on Elon Musk forming a new political party and his political activities but do not include any statements about Trump bankrupting the country. Therefore, while Musk has expressed concerns about fiscal policies linked to Trump-era legislation, there is no clear evidence he said Trump personally will bankrupt the country. This makes the claim false based on the available information.
