Republican Senator Rand Paul took a swipe at Elon Musk’s large family over President Donald Trump’s top legislative proposal, which he is calling the “Big not so beautiful bill.”Both Musk and Paul have expressed frustration with the bill as it stands, with Paul’s dislike being focused on its impact on government debt.Paul posted on X: “The legislation, as currently written, would pay someone like Elon Musk $1000 per child, and we know how prolific he is . . . No offense, Elon, but Is [sic.] that a wise use of our $$?”Paul did not expand on this post. The budget bill as it stands brings the Child Tax Credit (CTC) up to $2,200. This is not directly paying people to have children but is a tax incentive for people making under $200,000 a year.The libertarian senator from Kentucky may also have been referring to the children’s savings program portion of the bill, which would give every child born in America between 2025 to 2028 $1,000 in an investment account. This is putting money directly to a child’s account, not to their parents, so would not necessarily benefit Musk, who is father to at least 14 children, directly.Newsweek has contacted Paul via email for comment outside of working hours.Why It MattersPaul and Musk have been reposting each other’s comments about the impact of the bill on national debt, so Paul’s comment on X may have been an effort to highlight how the bill would add billions to the national debt, rather than an insult.The bill as it stands is not popular with American voters. According to a poll conducted by The Tarrance Group, which Paul has also shared, 58 percent of people agree with Musk’s assertion that the budget is a “pork-filled spending bill that will massively increase the budget deficit and burden American citizens with crushingly unsustainable debt.”The Trump administration says the bill is needed to address voter priorities. It seeks to permanently extend $3.8 trillion in expiring benefits while funding Trump’s mass deportation efforts with $350 billion in national security spending.What To KnowSenator Rand Paul has been one of the most outspoken Republican voices against the “Big Beautiful Bill,” as it stands.The bill passed a procedural vote in the Senate on June 28, with Paul and another Republican senator, Thom Tillis, voting against it.Paul has said he would be open to voting for the bill if it did not increase the debt, but it currently stands to add over $4 trillion, according to the Committee for a Responsible Federal Budget.Tax cuts in the budget bill are also expected to provide more tax benefits to the rich than the working or middle class. It will extend Trump’s 2017 tax cuts that resulted in reducing taxes significantly more for the top 0.1 percent, per analysis by the Tax Policy Center, Urban Institute, and Brookings Institution.The White House says that the bill “delivers for the American worker” and will deliver a “Blue-Collar BOOM.” It highlights measures such as a 15 percent tax cut for Americans earning between $30,000 and $80,000 per year, and no taxes on overtime or tips.Trump has also said that revenue generated from global tariffs will offset the reduction in tax revenue. The tax cuts in the bill as it stands are expected to add $4.6 trillion in debt, and tariffs are expected to generate up to $3.1 trillion, according to the Tax Policy Center, the Tax Foundation, and the Yale Budget Lab.Another Republican and libertarian legislator, Representative Thomas Massie, has criticized the “omnibus” nature of the bill, as it contains everything from tax credits to AI regulation in one package.Paul has agreed with this sentiment, saying on X: “Break up the bills so we can vote on individual matters, not a bunch of things at once.”What People Are SayingSenator Rand Paul on X: “I’ve said it before, and I’ll say it again: I’m willing to negotiate if the White House strips the massive $5鈥疶RILLION, long-term debt ceiling increase and replaces it with short-term extensions tied to real spending reforms. Fiscal responsibility isn’t a talking point. It’s a principle.”Daniel Hornung, former President Joe Biden’s deputy director of the National Economic Council, told The Guardian: “It’s really striking that this bill is both as fiscally irresponsible as it is and regressive. People making less than $50,000 a year will actually see their incomes go down, and it’s really to finance tax cuts for largely high-income people.”The White House, in a June 24 statement: “President Trump’s One Big Beautiful Bill lowers tax rates to keep more money in Americans’ pockets鈥擯REVENTING THE LARGEST TAX HIKE IN HISTORY.”What Happens NextThe budget bill just passed a procedural vote in the Senate without a single Democrat vote, or Senators Paul or Tillis. It still needs to pass another simple majority vote in the Senate, with Vice President JD Vance potentially needed as a tiebreaker. Then, it will return to the House for a final vote before it can be approved by the president.
