The Obama Administration is outraged that the Speaker of the House invited without prior approval the Israeli Prime Minister to address Congress. It is claimed that the action constitutes a violation of diplomatic protocol. But a breach of protocol is not necessarily a violation of law. It is not only protocol but a matter of constitutional provision that the actions of the Executive Branch be authorized by statutes enacted by the Legislative Branch rather than by fiat executive order. However, Obama certainly isn't that concerned with procedural precedent any other time.
