By Siobhan Hughes Of DOW JONES NEWSWIRES WASHINGTON (Dow Jones)--BP PLC (BP, BP.LN) Chief Executive Tony Hayward, facing lawmakers furious about an oil spill in the Gulf of Mexico, on Thursday allowed that some of the decisions "may have been to do with money." The U.S. House Energy and Commerce Committee on Monday wrote Hayward that its investigation showed that BP took shortcuts in developing the Macondo well in order to save time and money. The letter cited emails in which employees cited concerns about how long it was taking to drill the well and the need to be mindful of the "risk/reward equation." Hayward said that some decisions, "sitting here today, appear they may have been to do with money--it's not clear." -By Siobhan Hughes, Dow Jones Newswires; 202-862-6654; siobhan.hughes@dowjones.com (END) Dow Jones Newswires June 17, 2010 16:45 ET (20:45 GMT)
