WASHINGTON (AP) — Members of the Democratic-controlled Senate Judiciary Committee on Thursday sent to their colleagues a long-shot proposed change to the Constitution that would rein in political spending.

Democrats who lead the Judiciary Committee moved forward with an effort to limit deep-pocketed political campaign donors’ influence. Republicans called the proposal a political stunt aimed at rallying Democrats during this election year and a ploy to gin up populist outrage against wealthy donors who tend to side with conservatives.
