No shame: The executive director of Vice President Dick Cheney's energy task force, whose closed-door meetings with industry executives enraged environmentalists and prompted a Supreme Court showdown this week, became an energy lobbyist just months after leaving the White House, records show. Andrew Lundquist, a native Alaskan who worked on Capitol Hill for both his state's senators, shepherded the development of the administration's energy policy as executive director of the National Energy Policy Development Group, a Cabinet-level task force chosen by President Bush and headed by Cheney. When the task force completed its work, Lundquist stayed on at the White House as Cheney's energy policy director, leading the vice president's effort to turn the task force's work into law. Then, a day after leaving government service, he opened a consulting business. Nine months later, Lundquist was a registered lobbyist for companies that stood to benefit from the energy policy he helped craft, according to 2003 lobby disclosure records reviewed by the Globe.
