Musk, who officially left the White House last week, appeared to be pointing to estimates from budget experts who found that the Republican tax bill could add more than $2.5 trillion to the federal deficit in the coming years.

Elon Musk tore into the massive tax-and-spending-cut bill backed by President Donald Trump, calling it a "disgusting abomination."

"I just can't stand it anymore," Musk wrote. "This massive, outrageous, pork-filled Congressional spending bill is a disgusting abomination."
