Political ProfileWhere AON sits in Washington

[object Object]

STRUCTURAL: No lobbying spend (`get_political_influence.lobbying.total_income`: $0), no federal contracts (`get_government_precedent.federal_contracts_summary`: null), and no corporate insider buys (`Recent corp insider Form 4 buys`: []). EVIDENTIARY: Direct executive branch exposure via a Trump-held asset valued $15,001-$50,000 (`get_executive_branch_exposure.by_ticker[0].holdings[1].value_bucket`). Concentrated congressional trading shows net selling pressure (14 sales vs. 4 buys among 4 politicians in `Top congressional traders`). Net: Contradictory signals from executive holding vs. legislative sales and absent structural support.
