#TrumpVsMusk «I had a great relationship with Elon. I don't know if it will be the same now,» Trump told reporters at the White House on Thursday.

This was the most direct criticism of Musk from Trump for Musk (like several Republicans) calling one of Trump's main domestic policy initiatives, the "One Big Beautiful Law" on taxes and appropriations, an "abhorrent disgrace."

In response, Musk made even harsher statements on social media X, accusing the president of "ingratitude," adding: "Without me, Trump would have lost the election."

After the spat between Trump and Musk, shares of the billionaire's Tesla fell by 15% — the largest drop in a day in three months.
