• Members of Congress were set to make a few thousand extra bucks under a government funding bill.
• Then Elon Musk helped tank it.
• That's despite growing concern that it's becoming unaffordable to serve in Congress.

One of the most controversial pieces of the short-term government funding bill that Elon Musk helped tank last week was a provision that would have allowed members of Congress to receive a modest salary increase.

As Musk argued against the so-called continuing resolution in a stream of posts on X, he said lawmakers were set to receive a 40% salary increase if the bill passed.

In reality, rank-and-file members of the House and the Senate would have gotten at most a pay bump of $6,600, or 3.8% of their $174,000 annual salary, according to the Congressional Research Service.

Nonetheless, that provision wasn't included in the bill that emerged — and was signed into law — after two days of chaos on Capitol Hill.

That's despite growing sentiment from lawmakers in both parties that even if the optics are poor, increasing the congressional salary is necessary to ensure that less-wealthy people are able to serve and aren't lured away by higher salaries in the private sector.

Sen. Markwayne Mullin, an Oklahoma Republican and staunch supporter of President-elect Donald Trump, told reporters last week that the demands and responsibilities of the job made serving in Congress "not affordable" for those who weren't already wealthy like him.

"If we're not careful, you're only going to get the individuals that are millionaires-plus that's able to serve in Congress, and that's not what it's supposed to be," Mullin said. "It's supposed to be the people's house."

A $174,000 salary is far more than the average household income, but it hasn't budged since 2009. Accounting for inflation, lawmakers' salaries have essentially decreased by more than 30% in the past 15 years.

Members of Congress also face unique demands, including the need to maintain two residences: one in Washington, DC, the other in their home district. Those who can't afford it often opt to sleep in their offices. Experts have also said it's simply a matter of good governance: If lawmakers are paid well, they're less incentivized to cash out by becoming lobbyists after their tenure.

"I tell people the worst financial decision I ever made was running for Congress," Mullin said jokingly.

The provision tucked into the original funding bill technically was not a raise but rather allowed for an automatic cost-of-living increase originally established by the 1989 Ethics Reform Act. Those annual adjustments, which are typically single-digit-percentage salary increases, are designed to avoid the optics of lawmakers voting to increase their own pay.

Rep. Joe Morelle, the top Democrat on the House Administration Committee, sought to downplay the notion that members were receiving a raise. "It just complies with existing law," Morelle told BI last week. "There's nothing extraordinary about it."

Congress has nonetheless chosen to block those adjustments every year since 2009, owing to both inertia and the political unpopularity of increasing lawmakers' salaries. In March, a cohort of current and former lawmakers filed a class-action lawsuit over those denials, arguing that their wages had been "unconstitutionally suppressed."

The politics of raising wages on Capitol Hill remains toxic, however. As word spread on Wednesday about the cost-of-living adjustment in the bill, lawmakers in both parties came out against it.

"I cannot and will not vote to give myself more money when my constituents are feeling unbelievable financial pressure," Rep. Pat Ryan, a Democrat who represents a New York swing seat, said in a statement that day. "Congress should be focused on lowering costs for the American people, not giving ourselves a raise. If this provision isn't removed, I will be voting against the continuing resolution."

Ultimately, the cost-of-living adjustment was blocked once more.

Musk did not respond to a request for comment.

• Members of Congress may be getting an up to $6,600 raise this year.
• That's due to a provision in a must-pass funding bill that's set to get a vote this week.
• Rank-and-file lawmakers have been making $174,000 since 2009.

For the first time since 2009, members of Congress may be about to get a raise.

Under a provision tucked into a new bill to fund the government through March 14, lawmakers would be given a cost of living adjustment to their salaries — something that Congress has blocked every year for a decade and a half.

That could result in up to a $6,600 raise for rank-and-file members of Congress next year, according to a recent report from the Congressional Research Service.

Currently, most members of the House and Senate make $174,000 each year. Some congressional leaders make more than that, such as House Speaker Mike Johnson, who makes a $223,500 annual salary.

Though that $174,000 sum is well above the average household income, it hasn't kept place with inflation, and lawmakers in both parties have argued that it's not enough to keep up with the demands and responsibilities of the job, which can include maintaining two residences.

"If we want working class people who don't rely on independent wealth, to represent people in Congress, we have to make it work," Democratic Rep. Alexandria Ocasio-Cortez of New York told Business Insider earlier this year.

"You have quite a number of members of Congress that sleep in their offices," Republican Sen. Mitt Romney of Utah told BI earlier this year. "In this day and age, it makes sense to have people that feel that they can serve, and still be able to sleep in a home at night."

If Congress hadn't blocked annual cost of living adjustments since 2009, rank-and-file lawmakers would be making $217,900 this year, according to the Congressional Research Service.

Earlier this year, a group of current and former lawmakers filed a class-action lawsuit to recover money that they would have made if their wages hadn't, in their view, been "unconstitutionally suppressed."

Increasing lawmakers' salaries has long been politically unpopular, and the inclusion of the provision is already leading to some opposition from more politically vulnerable members.

Rep. Jared Golden, a Democrat who represents a GOP-leaning district in Maine, said in a statement on Wednesday that he wouldn't vote for the government funding bill unless a pay freeze was reinstated.

"Members of Congress earn more than 90 percent of Americans," Golden said. "If any of my colleagues can't afford to live on that income, they should find another line of work."

If Congress fails to pass the bill by Friday, the federal government will shut down due to a lack of funding.
