Center for AI Safety Action Fund — Lobbying Spend: $420,000

Note: The source URL points to the Senate LDA search page, but the excerpt provided contains only the HTML structure of a search form with country/region dropdown menus. It does not contain any actual LD-1 or LD-2 filing data, lobbying expenditure amounts, or specific information about Center for AI Safety Action Fund's spending. While the additional context claims the figure was 'verified from Senate LDA,' the actual source text does not display any such verification data. To confirm this claim, one would need to see the actual filing documents or search results from that database, which are not included in the provided excerpt.
