I don't know. Have Congress and Senate always been this ineffective? I don't remember Obama, Biden or even Trump 45 act with this much impunity. I obviously can't go further back because I have been here since Obama's second term.
The Iran-Contra scandal from the Reagan administration comes to mind. Congress explicitly de-authorized the executive from funding the Contras in Nicaragua. The executive kept doing it anyway. Nobody faced any consequences, though Congress at least made a lot of noise about it.
That's kind of ineffective, but not to this level where Congress is just fine with blatant illegality.
