Musk, the billionaire businessman behind Tesla and SpaceX, influenced several new Texas laws this year. How his lobbyists came about these wins, however, is more of a mystery.

His lobbyists, who represented Tesla, SpaceX and the social media giant X Corp., spent tens of thousands of dollars on things like gifts and meals for Texas elected officials and others during the session, according to an analysis of state ethics data. In most cases, Texas transparency laws do not require lobbyists to disclose which politicians they wined and dined or on behalf of which clients.

A slate of ethics bills, including several to require transparency into who funds mass text messages for political campaigns, failed to become law this year, according to The Texas Tribune. Meanwhile, legislators approved a new law that will reduce the fine for former lawmakers who engage in illegal lobbying activity.
