As chairman of the House Oversight and Government Reform Committee, his jurisdiction is so vast that it could potentially conflict with almost any source of income. Issa appears to avoid any obvious conflict because he does not own individual stocks. Most of Issa's investments last year were in two areas: high income mutual funds and companies that manage properties. Issa made his fortune as owner of the company that produces Viper car alarms. He no longer runs the firm, but remains a director of the parent electronics company, DEI Holdings. He also owns the company's corporate headquarters.
