Independently re-verified against congress.gov cosponsor pages. McClain took concrete, repeated action to advance estate-tax repeal: she was an ORIGINAL cosponsor (asterisk) of the Death Tax Repeal Act in the 117th Congress (H.R.1712, cosponsored 03/09/2021; sponsor Rep. Jason Smith R-MO) and again in the 118th Congress (H.R.7035, cosponsored 01/18/2024; sponsor Rep. Randy Feenstra R-IA). She did NOT cosponsor the 119th Congress version (H.R.1301, sponsor Feenstra) — confirmed by zero occurrences of her member link in that bill's cosponsor list. The federal estate tax was never repealed and none of these repeal bills received a floor vote, so the promise did not land despite her genuine, repeated support. She advanced the effort as one of ~150-180 cosponsors rather than sponsoring/leading/driving it, which places this at ATTEMPTED, not CHAMPIONED or FULL. This is the same standard that would apply to a member of either party who cosponsored a bill that never passed. (Minor correction to prior rationale: the 117th bill's lead sponsor was Jason Smith, not Feenstra; Feenstra led the 118th/119th versions. Not outcome-affecting.)
