We need to hold our representatives feet to the fire, but I think our hands are tied.

I don't think there is any path provided by the constitution for recalling US senators, (except in the case of breaking some laws), but if your republican senator get's this impeachment trial vote wrong, call local state legislature representative to legislate for sanctions against those senators.

States could create state laws that penalizes a senator at the state level for failing to resign in a period of time after some sort of public in state vote calling for the state senator to resign. Potentially even subjecting to jail time for failure to resign.

Any legal/constitution experts please chime in.
