No House member has disclosed a ALGM trade since 2025.
From the House's STOCK Act reports (Senate not included). Members disclose trades, not holdings, as value ranges up to 45 days later, so amounts are estimates and “last move” is a hint at who still holds it, not a position. All recent congress trades
