Bills Affecting MPCLive legislation impacting this stock

Political ProfileWhere MPC sits in Washington

[object Object]

STRUCTURAL: High regulatory density from 8 energy-sector bills (`Recent bill_impacts`). EVIDENTIARY: No corporate insider buys (`get_corporate_insider_signal.top_buys` empty), no federal contracts (`get_government_precedent.federal_contracts_summary` null), and no lobbying spend (`get_political_influence.lobbying.total_income` 0). Active but mixed-direction congressional trading present (`Top congressional traders`). Net: Structural regulatory risk offset by lack of evidentiary financial alignment from insiders or government.
