Lawrence B. "Larry" Lindsey (born July 18, 1954) is an American economist. He was director of the National Economic Council (2001–2002), and the assistant to the president on economic policy for the U.S. President George W. Bush. He played a leading role in formulating President Bush's $1.35 trillion tax cut plan, convincing candidate Bush that he needed an "insurance policy" against an economic turndown. He left the White House in December 2002 and was replaced by Stephen Friedman after a dispute over the projected cost of the Iraq War. Lindsey estimated the cost of the Iraq War could reach $200 billion, while Defense Secretary Donald Rumsfeld estimated that it would cost less than $50 billion.
