WASHINGTON, April 22 (UPI) -- The U.S. Justice Department announced it formed a working group to evaluate possible manipulation of oil and gasoline prices as well as the role of speculators.
U.S. President Barack Obama, in a speech in Virginia this week, said it's not a lack of supply that is driving oil prices up on the commodity markets. He said speculators in the energy market are making investment decisions that cause prices to spike "significantly."
