Mast voted against the infrastructure bill as a 'socialist wishlist' but then publicly demanded that the Biden administration allocate Everglades restoration funding from the very same bill — a project he previously said needed $725 million in federal infrastructure investment. He took credit for pushing the Army Corps to fund the project after voting against the funding mechanism.

Expected position: As the newly elected chairman of the House Foreign Affairs Committee, Mast would be expected to address concerns raised by members of his own party and detractors about wearing an Israeli military uniform in the Capitol building, which a GOP primary challenger called 'traitorous' and which critics argue compromises his ability to conduct impartial foreign policy oversight. Evidence of activity on adjacent topics: Mast wore his IDF uniform to the Capitol on October 13, 2023, days after the Hamas attack. When asked about it, he deflected with a comment about Rep. Rashida Tlaib. His GOP primary challenger in 2024 called him a 'traitor.' Mast subsequently leaned into the controversy, tweeting in 2026 that he was 'proud to be the only member of Congress who has worn both the uniform of the United States Army and the uniform of the Israel Defense Forces.' During the months after becoming HFAC chairman, he has not addressed how this dual-loyalty perception might affect his committee's work on Middle East policy.

[ Show full donor-interest summary ]
Expected position: As a member of the House Transportation and Infrastructure Subcommittee on Aviation with oversight authority over aerospace companies, Mast would be expected to address his failure to disclose up to $100,000 in Virgin Galactic stock within the legally required 45-day window — a purchase made weeks after Virgin Galactic's president testified before his subcommittee. Evidence of activity on adjacent topics: Mast missed the deadline to disclose the Virgin Galactic stock purchase. When Business Insider broke the story on August 16, 2022 documenting the violation alongside Sen. Rick Scott, Mast did not return a request for comment. He was active on social media and in committee hearings throughout this period. Florida Politics also reported that Mast's office 'did not immediately respond to a request for comment' regarding the STOCK Act questions.

Scoring Methodology

The Capture Risk Score is a composite 0–100 index measuring potential regulatory capture of elected officials. It is computed from seven weighted components:

ComponentWeightSignal
Contradiction Risk30%Stated positions contradicted by the record (recent findings boosted)
Donor Influence20%Distinct documented donors (FEC Schedule A PACs); inferred donors do not count
Connection Density20%Mapped relationships to lobbyists, contractors, interest groups; donor links excluded
Silence Risk15%Topics where donors have interests but the official is silent
Intelligence Volume15%Documented facts from verified sources
Constituency Deviation0%Shown, not weighted — a model estimate, not a record
Voting Misalignment0%Shown, not weighted — needs platform commitments almost nobody has; the roll-call record on /votes is the vote signal

Each component is the member's standing among all scored members of Congress, and the weighted sum is the overall score. Tiers are ranks: Critical is the top 5%, High the next 10%, Elevated the next 20%, Moderate the next 30%, and Low the rest.

Officials without at least 2 documented facts, 1 contradiction analysis, 1 voting record, or 1 constituency baseline are marked Insufficient Evidence and excluded from numeric ranking.

Contradiction findings from the last 180 days receive a recency boost. High-severity contradictions (score ≥ 70) receive additional weight.

Calculation Methodology

Contract values are summed from documented money flow chains where this entity appears as a source or destination node. Amounts are drawn from USASpending.gov, FEC filings, SEC EDGAR, or LD-2 lobbying registrations.

Donor contributions aggregate documented amounts from the donor_interests table, sourced from FEC individual and PAC contribution filings.

Connected officials are elected officials in our database with a mapped relationship (lobbying, board membership, campaign contribution, etc.) to this entity.

Annualised flow represents the total documented dollar amount traced through money flow hops involving this entity. Where hop-level amounts are unavailable, the chain-level documented total is used as a conservative upper bound.

All figures are drawn from public filings. Estimates are conservative — undisclosed transactions, dark money, and vanish-point hops are excluded from totals. This is a minimum documented floor, not a ceiling.
