By a vote of 396-22, the House approved new lobbying reform legislation on May 24 when it passed the Honest Leadership and Open Government Act of 2007 (H.R. 2316). The bill increases the reporting requirements for registered lobbyists, establishes a new electronic disclosure system, imposes new penalties for violating lobbying laws, and includes the controversial proposal to require registered lobbyists to report their bundled campaign contributions (H.R. 2317). The bill will now go to conference committee with a similar Senate bill that was passed in January.

At least 12 states are considering developing regulations for vehicle greenhouse gas emissions that would exceed federal standards. These states cannot promulgate the rules because the primary federal framework for air pollutant regulation, the Clean Air Act, reserves the federal government's right to block state efforts. Critics are charging the Bush administration with impeding the environmental progress of states and delaying meaningful regulation of vehicle emissions.
