Elon Musk's feud with President Donald Trump — and seemingly any congressional Republicans who support the president's massive tax cuts and spending package — has reignited, with the tech billionaire threatening to launch a new political party,

Musk has taken issue with the bill saying that it flies in the face of everything he thought he was supporting. Trump appointed Musk to head up the newly formed Department of Government Efficiency and was tasked with reducing “waste, fraud, and abuse” in government spending.

Elon Musk renewed his calls Monday for a new political party as he lodged sharp criticism against President Trump’s megabill as the Senate seeks to move toward a final vote on the reconciliation package.

U.S. Senate Republicans were struggling to pass President Donald Trump's sweeping tax-cut and spending bill early on Tuesday, amid deep divisions within the party about its expected $3.3 trillion hit to the nation's debt pile.

Senate Republicans can afford to lose no more than three of their own votes on the bill, but two already are opposed and others remained undecided.

Proponents maintain that the opportunity to pass President Trump’s core agenda items—and pressure from Trump on holdouts—would propel the package over the finish line in the Senate, where the GOP has a 53-47 majority.
