WASHINGTON/HOUSTON (Reuters) - BP Plc's U.S. chief faces accusations in Congress on Tuesday that the energy giant caused the worst oil spill in U.S. history with a calculated strategy to cut costs, hours before President Barack Obama uses a televised address to defend his handling of the disaster.
A day after BP shares fell 9 percent in London and New York and the company hired investment bankers for undisclosed reasons, U.S. lawmakers will ask Lamar McKay why BP made repeated choices that appeared to favor cost savings over safety before its rig blew up in the Gulf of Mexico.
