According to the Internet, according to the Wall Street Journal, Trump seemed to have lost patience with Musk after Musk attacked the Republican Party's huge tax and spending bills. At the same time, Musk was annoyed by Trump's decision to withdraw his nomination of a key ally to lead NASA. A senior White House official said Trump was unhappy with Musk's decision to berate the bill he signed, saying the president was confused by Musk's decision to step up his criticism after four months of working closely with him. The official said Trump's top advisers were caught off guard by Musk's latest offensive. According to people familiar with the matter, the White House's recent move to veto Trump's nomination for NASA Administrator Jared Isaacman also strained the unstable alliance between the two men. A person with direct knowledge of the matter said the decision angered Musk, who complained to colleagues over the weekend that he had donated hundreds of millions of dollars to help Trump get elected in last year's campaign, only to see Isaacman's nomination revoked. People close to Musk said his disappointment with the NASA incident made him more willing to actively criticize the tax bill.
