Congressional portfolios keep gravitating toward companies their committees oversee and toward defense and health contractors moving on federal money — even as insiders unloaded more than $2 billion of a single AI-adjacent name in a day.

• Health insurer $UNH drew the deepest congressional bench, with 11 members trading (28 buys to 11 sells) — including one committee-sector overlap — against a backdrop of Federal Contract signals on the same ticker.
• Defense-and-contracts cluster: $BA (8 members) and $HII (2 members) both traded amid Federal Contract signals, while insiders at defense firm $KTOS sold ~$38M led by President & CEO Eric DeMarco.
• Big Tech remains the consensus crowd favorite — $MSFT (22 members, 45 buys/32 sells, 9 committee-sector overlaps) and $AAPL (22 members, 7 overlaps) — even as Nancy Pelosi disclosed an $AAPL sale of $5M–$25M.
• On the insider tape, Magnetar Financial logged 295 open-market sales of $CRWV worth roughly $2.38B in a single day, dwarfing Cascade Investment's ~$235M purchase of waste hauler $RSG the same session.
