Cupich and Tobin. They represent an extremely liberal and certainly non orthodox perspective.
Secondly, i assume that you are asking whther McElroy himslef should have communion withheld for his view. The answer to that is of course not unless he is intentionally pushing for the abuse of the sacrament rather than coming to his views honestly. Because there is no clear action that represents a loss of grace, there would be no reason for a priest to withhold communion from mcElroy. Now if McElroy had bad intentions with his public stance (for instance to push a pro abortion agenda). then he would be obligated as a Catholic to refrain from communion. The decision to protect the eucharist falls to the priest who is there at the mass, and in cases where the person is known to be engaging is clearly evil actions constituting mortal sin, then the priest is obligated not to give communion to that person and protect the Eucharist from abuse. (Certainly, God does not need protection, but the Body of Christ is deserving of such respect).
