Senate Republicans Monday afternoon argued to [Senate Parliamentarian Alan] Frumin that a provision of the reconciliation package approved by the House violated Section 310g of the Budget Act....Frumin heard arguments from Democratic and GOP Senate staff, and he ultimately ruled in favor of the Democrats. The Republicans argued that a provision dealing with the excise tax on “Cadillac” insurance plans impacted Social Security. The Budget Act does not permit reconciliation legislation to affect Social Security.
....“One down, many more to go,” a GOP aide said Monday evening.
That was quick. Republicans may have "many more to go," but if they're all as laughable as this one they'd better get used to rejection.
