4/6 components have data
#48 of 193 scored

Roger Marshall (R-KS), a physician elected to the House in 2016 and the Senate in 2020, has a moderate record of individual-stock activity tied to his household, including a documented STOCK Act late-filing: stock purchases (Chevron, Disney) by his dependent children in 2020 were disclosed in September 2021, more than a year past the 45-day deadline. Quiver Quantitative parses up to roughly $5.7M of trades from his filings, though much of his wealth sits in a spouse-held private company (Farmers Enterprises) and mutual funds rather than actively traded single stocks. His campaign donor base concentrates in health/pharmaceutical and agriculture industries that overlap his Senate HELP and Agriculture committee seats, a correlation (not proof) of influence given his drug-pricing and ag positions. No public records were found of campaign-fund personal use, family lobbying/contracts, or a staff-to-lobbyist pipeline, and his vote-attendance record (~2.9% missed) is on par with the Senate median, so those components score low for absence of evidence rather than a clean affirmative finding.

The stock-trading ban

Senate cloture on H.R. 7008, Sep 30, 2026
Yes
Cosponsored a ban bill
S. 4134

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 →

Disclosed stock trades

No periodic transaction reports on file since 2024. That's the norm: most members don't trade individual stocks, or hold them in blind trusts and diversified funds.

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-trading
25% weight
38
Household holds and trades individual stocks; Quiver parses up to ~$5.7M of trades. A confirmed STOCK Act violation: dependent children's 2020 Chevron/Disney purchases (up to $15K each) disclosed Sept 2021, >1 year late. Holdings span Twitter, Microsoft, Alibaba, Treasuries. Some sector overlap with finance/health committee work, but no documented evidence of trades timed to nonpublic information or systematic market-beating returns.
Net-worth enrichment in office
15% weight
18
OpenSecrets estimated ~$7.3M net worth (2018); 2019 disclosure showed assets of $3.9M-$12.2M and a midpoint estimate near $3.8M. Most wealth is a spouse-held private company (Farmers Enterprises, $1M-$5M) and mutual funds predating office. Ranges are wide and overlapping; no clear evidence of growth beyond salary/market attributable to office. Much is pre-office wealth, which is not scored.
Money → action alignmentcorrelation, not proof of any quid-pro-quo
20% weight
40
CORRELATION, NOT PROOF. Marshall, a physician, sits on the Senate HELP, Agriculture, and Finance committees; his donor base concentrates in pharmaceutical/health-products and agribusiness industries that those panels regulate. His positions favor industry-aligned outcomes on drug pricing and Medicaid. The donor-committee-sector overlap is structural; no specific quid pro quo is documented.
