The House passed HR.2478, the Financial Exploitation Prevention Act of 2025, on June 25, 2026, by a vote of 414 to 2. It is, by any measure, a bill about financial services. Mastercard Incorporated is, by any measure, a financial services company. Three sitting members of Congress hold Mastercard in their disclosed portfolios. Two of them voted yes. The third didn't vote at all. The public record is right there, searchable, timestamped, and minding its own business.
The Bill, Briefly
HR.2478 cleared the House 414-2. Two members voted no. Two. In a 435-seat chamber where members can't agree on the color of the carpet, this bill got 414 yeas. Whatever the Financial Exploitation Prevention Act does for the financial services sector, the House was extremely enthusiastic about it.
The bill targets financial exploitation, broadly construed. The sector it touches is Financial Services. The industry it most directly implicates is Credit Services. Mastercard Incorporated operates squarely inside that industry — it processes credit transactions for a living. The overlap between "legislation affecting credit services" and "Mastercard" is not complicated.
Members are required to disclose their holdings. They are not required to divest, recuse, abstain, or look up from their phones. That's the system.
The Three Names on the Filing
Per the disclosure records, three current members of Congress hold Mastercard (MA) in their portfolios: Michael McCaul, Ro Khanna, and Shelley Moore Capito.
McCaul voted yes.
Khanna voted yes.
Capito did not vote.
Two of the three were in the yes column on a financial services bill while holding a credit services company in their portfolios. The third is a Senator from West Virginia, which means she was not casting a House vote regardless of her holdings. Senate members don't vote on House floor proceedings. She's in the disclosure record. She's not in the vote record. Those are two different records.
McCaul: Mastercard, Texas, and a Long Filing History
Michael McCaul is a Republican from Texas's 10th district, a former chairman of the House Foreign Affairs Committee, and someone whose financial disclosures have drawn attention before for their breadth. He voted yes on HR.2478.
The Mastercard holding is one line item in a filing that tends to run several pages. But it's the line item that's relevant here. He held Mastercard. He voted on a bill touching Mastercard's sector. The calendar puts those two facts in the same week.
414 members voted yes. McCaul was one of them. A near-unanimous vote doesn't dissolve the underlying structural question about who's holding what while they're deciding what.
Khanna: Silicon Valley Progressive, Mastercard Shareholder
Ro Khanna represents California's 17th district, the heart of Silicon Valley, and has built a public identity around economic populism, workers' rights, and being the Democrat most likely to quote a 19th-century economist on the House floor. He also holds Mastercard.
He voted yes on HR.2478.
The portfolio-versus-persona gap is worth naming. Khanna has made carrying water for the working class a core part of his brand. Credit card companies are not typically cast as the working class's best friends. Mastercard collects interchange fees from merchants on every swipe, those costs get passed to consumers, and the whole architecture of the credit system is something Khanna has rhetorically positioned himself against in other contexts. The holding is there. The yes vote is there.
To be precise: voting yes on the Financial Exploitation Prevention Act is not the same as voting to hand Mastercard a subsidy. The bill's framing is about protecting consumers from financial exploitation. Khanna voting yes is arguably consistent with his stated positions. But the portfolio disclosure sitting alongside the vote disclosure is exactly the kind of context the disclosure regime was designed to surface. It's surfaced. Readers decide what to do with it.
Capito: The Senate Holder Who Couldn't Vote
Shelley Moore Capito is a Republican Senator from West Virginia. She's in the Mastercard disclosure. She is not in the HR.2478 vote record, because HR.2478 was a House vote and Capito is a Senate member. She didn't fail to vote. She was not there to vote. The distinction is worth making explicitly so the data doesn't mislead.
Capito's presence in this story illustrates that the disclosure universe for a financial services bill is broader than just the chamber taking the vote. The Senate will eventually see a version of this legislation, or related legislation, or appropriations riders touching the same sector. At that point, her Mastercard holding becomes directly relevant to a vote she will actually cast. The filing doesn't expire when a bill clears one chamber.
The 414-2 Problem
A 414-2 vote makes the conflict-of-interest question structurally harder to isolate. When a bill passes by two votes, the holder in the yes column is potentially determinative. When a bill passes by 412 votes, any individual yes is arithmetically irrelevant to the outcome. McCaul and Khanna's yes votes didn't shift the picture. The bill was never in doubt.
But that framing lets the system off too easy. The question is not whether any individual vote was decisive. The question is whether members who hold financial stocks are participating in deliberations and votes about financial legislation while holding those stocks. Per the public record, they are. The margin was 412 votes, but the filings read the same either way.
It's legal. That's the part that should bother you.
What the STOCK Act Does and Doesn't Do
The Stop Trading on Congressional Knowledge Act, passed in 2012, requires members to disclose trades within 45 days. It does not require divestiture. It does not require recusal. It does not prevent a member from voting on legislation affecting a company they own stock in, as long as that member reports their trades on time. The disclosure obligation is real. The consequences of disclosure are largely theoretical.
The three Mastercard holders in this story are, by all available evidence, complying with the law. Their holdings are disclosed. Their votes are on the record. The STOCK Act is functioning exactly as designed. Whether the design is adequate is a separate question — one that 414 members of Congress have notably not rushed to revisit.
The people most positioned to strengthen the recusal rules are the people who would be most constrained by stronger recusal rules. The institutional deadpan writes itself.
The Sector Overlap
Three Mastercard holders. One House vote on a financial services bill. Two yes votes from the holders who were in the chamber. One Senate holder who couldn't cast a House vote. The bill passed 414-2 — the yes side won by 412 votes even subtracting both Mastercard-holding House members from the tally. The bill's effect on Mastercard's specific business lines is a question for analysts, not this publication. What's not a question is that Mastercard is a Credit Services company, HR.2478 is a Financial Services bill, and three members of Congress hold the stock.
The disclosure system put both facts on the same page. We're just reading it.
The receipts are public. Make of them what you make of them.
