HOUSTON, United States

Elon Musk continued his crusade to convince lawmakers to kill President Donald Trump's tax and spending bill, which is estimated to add $2.42 trillion to US budget deficits over the next decade.

"Bankrupting America is NOT ok!" Musk posted Wednesday on his X social media platform, where the billionaire Tesla and SpaceX CEO has more than 220 million followers.

"Call your Senator, Call your Congressman," he continued, with the US Senate needing to approve the bill before the president can sign it into law.

The US House of Representatives narrowly approved the spending bill last month, but the Congressional Budget Office (CBO) on Wednesday released its estimate of what it would cost taxpayers if signed into law: a staggering federal debt of nearly $2.5 trillion.

Musk, who recently stepped down as the head of Trump's Department of Government Efficiency (DOGE), an initiative aimed at reducing federal spending, blasted the president's proposal, saying the "massive, outrageous, pork-filled Congressional spending bill is a disgusting abomination."

The CBO’s calculation of Trump's so-called One Big Beautiful Bill reflects a $3.67 trillion decrease in expected revenues and a $1.25 trillion decline in spending over the decade through 2034, relative to baseline projections.

But Democrats and conservative Republicans -- including Musk -- are concerned that the bill could threaten the US economy.

"KILL the BILL," said Musk.

Trump administration officials have repeatedly dismissed CBO projections as inaccurate and have countered that the plan will boost economic growth "north of 3%" by this time next year.

But the bill faces opposition by both parties in the Senate, where multiple lawmakers have expressed a desire to make changes to the president's plan.

Trump is expected to meet with Senate Finance Committee members to discuss the bill before the full Senate takes its vote.
