The FCC is not part of the executive branch – it is an independent commission that is accountable to Congress. The only authority the FCC has is to do those things delegated to it by Congress by law and contained in the Code of Federal Regulation in Section 47
Recently departed FCC Chairman Tom Wheeler, knowing he had two flunkies that would vote for anything, started creating new powers for the FCC not authorized by Congress, the largest being Net Neutrality. The wide ranging proposals were not shown to the two Republican commission members and put into effect with minimal public comment. Rather than fight in the courts, Congress is undoing Wheeler’s usurpation of regulation of the Internet.
