#137 of 193 scored

Rep. Doris Matsui (D-CA, in office since 2005) sits on the powerful House Energy and Commerce Committee, serving as ranking member of the Communications and Technology Subcommittee. Public trackers (Capitol Trades, Quiver Quantitative) show no record of individual-stock trading by Matsui or her spouse, so STOCK Act self-dealing risk appears minimal. Her sizable disclosed wealth stems largely from her 2020 marriage to AES Corporation co-founder Roger Sant — pre-marriage spousal wealth that is not enrichment from office, though AES's energy-sector profile creates a notable (un-recused) overlap with her committee jurisdiction. Her fundraising is heavily PAC-driven and concentrated in telecom, pharma, and other Energy and Commerce-regulated sectors (correlation, not proof of vote-buying); no campaign personal-use allegations, ethics findings, or notable attendance problems were identified (1.1% missed votes, better than the median).

H.R. 7008 bans new stock purchases by members, spouses and dependents; it doesn't force sales of existing holdings. The Senate vote was on the version paired with the SAVE Act, which is why no Democrat voted yes. Full breakdown →

Amounts are the ranges members must report, not exact values. The STOCK Act requires a report within 45 days of a trade; "late" counts days past that deadline, measured to the filing date.

How the score breaks down

Stock self-tradinghousehold / spouse
25% weight
0
No record of individual-stock periodic transaction reports (PTRs) for Matsui or her spouse on congressional trade trackers; her disclosed assets historically are funds, muni bonds, and bank deposits, not actively traded individual equities.
Capitol Trades maintains a profile for Matsui but shows no individual-stock trade activity.Data aggregatorcapitoltrades.com ↗2018 disclosed assets were a credit-union account, a Deutsche Bank deposit program, and a limited-term muni bond fund — not individual stocks.Reference databaseopensecrets.org ↗
Net-worth enrichment in office
15% weight
12
Matsui's net worth jumped sharply after her 2020 marriage to AES Corp co-founder Roger Sant, making her one of the wealthier House members. This gain is spousal/pre-marriage wealth (largely excluded from scoring), not growth from her salary or trading; partial score reflects only the un-recused overlap between that energy fortune and her Energy and Commerce role, not evidence of office-driven enrichment.
Matsui's sizable wealth gains came from her 2020 marriage to AES Corporation co-founder Roger Sant; her wealth comes primarily from him.News reportingtriad-city-beat.com ↗Pre-2020 OpenSecrets estimates put her net worth around $1.3M (2018), indicating the later jump is marriage-driven.Reference databaseopensecrets.org ↗

CORRELATION, NOT PROOF. Matsui is consistently a top recipient from the telecom/communications sector she oversees, and roughly 70% of her 2024 contributions came from PACs (about 2% small-dollar). Top industries lobbying her office (telecom, pharma, defense) mirror her Energy and Commerce jurisdiction; no specific quid-pro-quo evidence found.

OpenSecrets maintains a revolving-door profile for Matsui (typical of long-tenured members whose former staff move into lobbying), but specific named staff-to-lobbyist pipelines or family-lobbying contracts tied to her office were not confirmed in accessible records. Low score reflects only the general presence of a tracked profile, not documented abuse.

Strong attendance: missed only 154 of 13,804 roll-call votes (1.1%) from 2005-2026, better than the ~2.1% median for sitting representatives. Heavy PAC fundraising exists but is not paired with vote-skipping or reported paid-speech abuses; low score reflects fundraising intensity alone.
