A former official in the Clinton administration has been named director of the office of international trade and development for the city of Los Angeles. Andre Winston Lewis, who assumes a newly created office, will oversee three senior trade specialists who will be involved in attracting and retaining foreign investment, promoting exports and assisting business and trade groups to enhance international trade efforts. Lewis, who was appointed to the post by Mayor Antonio Villaraigosa, was most recently deputy cabinet secretary for former Gov. Gray Davis. Prior to that, Lewis held posts in the Department of State, working on environmental issues and economic and national security issues related to the independent states of the former Soviet Union under President Clinton.
