Official portrait of Chuck Grassley

Chuck Grassley

R Republican · Senator, Iowa

Low self-dealing
5/6 components have data
#148 of 193 scored

Chuck Grassley (R-IA), in the Senate since 1981, presents a notably clean self-dealing profile. His disclosed assets are dominated by Iowa farmland (largely pre-office/inherited family farm) and diversified mutual funds, with no public record of individual-stock STOCK Act trading, which removes the most common conflict-of-interest vector. He holds the longest perfect-attendance voting streak in Senate history (no missed vote since 1993), undercutting any job-versus-fundraising concern. The main flaggable items are correlation-only: large career donations from pharmaceutical, insurance, and health-professional industries alongside his health/drug-pricing committee work (though his drug-pricing record is largely bipartisan and consumer-oriented), and isolated staff revolving-door instances common to long-tenured senators; none rise to documented self-enrichment.

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
0
No public record of individual-stock STOCK Act periodic transaction reports. Disclosed holdings are Iowa farmland and diversified mutual funds (e.g., MRFIX, IGFFX, GSFTX, PRCOX), not individual equities. Per rubric, 0 when no individual-stock trading.
Net-worth enrichment in office
15% weight
10
Net worth estimated $5M-$8M (varying sources). Wealth is concentrated in family farmland valued $1M-$5M (largely pre-office/inherited) plus mutual funds and farm income (~$235K/yr); no evidence of growth beyond salary, farm income, and market returns. Pre-office farm wealth is not scored.
Money → action alignmentcorrelation, not proof of any quid-pro-quo
20% weight
30
CORRELATION, NOT PROOF. Top career donor industries are health professionals (~$1.0M), insurance (~$1.0M), lawyers (~$626K), and pharma/health products (~$539K); top donors include Blue Cross Blue Shield and Amgen. Overlaps his health/judiciary work, but his prescription-drug-pricing record is largely bipartisan and consumer-oriented, weakening any quid-pro-quo inference.
Campaign-fund personal useno data
15% weight
—
No public records found documenting campaign or leadership-PAC funds spent for personal benefit. Per rubric, absence of evidence is not penalized.
Revolving door & family
15% weight
20
Staff-to-lobbyist pipeline instances exist, common to long-tenured offices: legislative director Kurt Kovarik left for the National Biodiesel Board, with reporting that he worked on biodiesel matters around the transition (an ethics expert noted an appearance of conflict). No documented family-lobbying enrichment or contracts tied to Grassley's office.
Skips the job to fundraise
10% weight
0
Holds the longest perfect-attendance voting streak in Senate history, having not missed a recorded vote since 1993. No evidence of fundraising/paid speeches displacing legislative duties.
