#35 of 193 scored

Mario Diaz-Balart (R-FL), a senior House Appropriations Committee member first elected in 2002, shows a modest individual-stock trading footprint (roughly $145K in disclosed trades, mostly older, e.g., 2017 sales of HPQ/AMZN/HPE) with no documented suspicious-timing scandal. His most notable accountability issue is a long-standing family revolving-door pattern: his brother, former Rep. Lincoln Diaz-Balart, has earned over $2.5M lobbying for Taiwan and Morocco — both countries Mario advocates for in Congress — though contracts formally bar lobbying his office, and a nephew (Daniel Diaz-Balart) also entered lobbying. Campaign funding is heavily PAC- and pro-Israel-concentrated (AIPAC-aligned ~$516K career), a correlation worth noting given his appropriations/foreign-aid role but not proof of quid pro quo. His lifetime missed-vote rate (4.6%) is roughly double the chamber median, and reported high-dollar campaign meal spending warrants monitoring but no confirmed personal-use violation.

The stock-trading ban

H.R. 7008 passage, Jul 22, 2026
Yes
Cosponsored a ban bill
None

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.

Correlation, not proof. Funding is ~45% PAC and heavily concentrated in pro-Israel interests (AIPAC ~$480K, pro-Israel total ~$516K career), aligning with his Appropriations foreign-aid role and consistent advocacy. Concentration is notable but no documented vote-for-cash evidence.
