Following the death of Herman Brown, Halliburton acquired Brown & Root in December of 1962. According to Dan Briody, who wrote a book on the subject, the company became part of a consortium of four companies that built about eighty-five per cent of the infrastructure needed by the Army during the Vietnam War. At the height of the war resistance movement of the '60s, Brown & Root was derided as "Burn & Loot" by protesters and soldiers.
In October 2003 members of Congress Henry Waxman (D-CA) and John Dingell (D-MI) demanded an investigation in the high prices that are asked for the oil that is sold in Iraq. The firm was importing Kuwaiti oil for 23 eurocents a liter, which shouldn't have cost the US government no more than 60 eurocents according to experts. The US was selling this oil for 3,400 eurocents a liter.
