The movie Iraq for Sale: The War Profiteers claims that Lesar has been paid over $42,000,000 by Halliburton since the beginning of Iraq war, but this amount has risen significantly since the release of the film. According to the Wall Street Journal Lesar received about $14.9 million in 2010 alone, not including stock options or other deferred incentives - a 20% increase over his 2009 pay package, according to a securities filing.
In November 2014, Lesar faced criticism over his bid to take over Baker Hughes Inc : "the smaller oil-field services rival, in an email to Mr. Lesar, described Halliburton’s actions as intransigent and inappropriate".
