Washington (CNN) -- Rep. Edward Markey on Monday challenged the assertion by oil giant BP's chief executive that no underwater oil plumes have formed because of the Gulf of Mexico spill.
In a letter to BP, Markey, D-Massachusetts, said scientific evidence showed that such plumes have formed, and he asked for BP CEO Tony Hayward to provide evidence to back up Hayward's claim Sunday that the oil had gone to the surface.
On Sunday, Markey, who heads the House Energy and Environment subcommittee, accused BP of issuing false statements about the spill.
"BP in this instance means 'Blind to Plumes,' " Markey said in a statement Monday.
