Pass special interest group reform through the Congress. Involve the Judicial Branch of government if Congress refuses to consider it. All three branches of the government are intended to represent the people not whoever has enough money to fund their political aspirations.
Congress has been considered corrupt from lobbyist money for generations. The people are promised campaign reform repeatedly by many politicians on their way into office. Clearly, this is not an easy bill to get to passed and has met resistance on both sides of the isle. Resistance from Congresspersons whom are receiving special interest money is no reason to stop pushing for reform, no matter the amount of resistance.
Congress should make no law that puts the interest of one above the interest of all.
