Kyrsten Sinema is represented in this repository as a former Arizona senator whose campaign-finance records, joint-fundraising structure, post-Senate advisory roles, and financial-regulatory issue positioning provide a bounded comparison case for Jessica Killin. The current repo evidence supports donor-class, employer, vendor, and issue-network comparison, but it does not support a direct personal or operational relationship between Sinema and Killin.
The retained Sinema source layer is intentionally narrow. It was created to test whether Jessica Killin's donor and fintech / financial-regulatory network overlaps with Sinema through direct donors, donor-employer clusters, campaign vendors, fundraising vehicles, policy communities, or post-office intermediaries.
The strongest source basis is OpenFEC. Sinema's 2024 cycle Senate candidate ID is S8AZ00197; her principal committee is SINEMA FOR ARIZONA (C00508804), and the retained comparison also includes SINEMA LEADERSHIP FUND (C00789834), a joint fundraising committee. The post-office source layer adds a narrower intermediary context: Coinbase announced Sinema's Global Advisory Council role in January 2025, Hogan Lovells announced her March 2025 senior-advisor role in its Global Regulatory & IP practice group, and an official Senate page lists her post-employment lobbying restriction period as 2025-01-03 through 2027-01-02. A follow-up LDA check found no Kyrsten Sinema / Sinema lobbyist-name results in the queried 2025-2026 set, and found one stronger intermediary bridge through shared donor Steven Elmendorf, Avoq, and Coinbase.
