Michael McCaul — disclosures (Semiconductor Caucus co-chair's AI/chip book)
Rep. Michael McCaul (R-TX-10); among the wealthiest in Congress (portfolio >$100M, largely via his wife's Clear Channel family wealth). Co-chair of the Congressional Semiconductor Caucus and member of the AI + Cybersecurity Caucuses. Disclosed via STOCK Act PTRs.
The most on-the-nose policy/portfolio overlap on the page: McCaul literally co-chairs the Semiconductor Caucus and writes chip policy, while trading the exact AI value chain — NVDA, ASML (sole EUV-lithography supplier), and the AI-power names (GE Vernova, Corning) that were primary beneficiaries of the 'Clean AI Energy' proclamations. A huge, high-turnover book ($79.7M 2025 volume, 46 transactions in a single Dec-2025 filing) spanning AI-semi single names, fixed income, and muni-bond ETFs.
