Matthew Simmons is sticking by his story that there's another giant leak in the Gulf of Mexico blowing massive amounts of oil into the Gulf of Mexico.

On CNBC's Fast Money, he says he'd be surprised if BP lasted this summer, saying this disaster is entirely BP's fault.

Simmons has been all over cable news lately -- yesterday he described to Dylan Ratigan how the next nightmare will be when a Hurricane picks up the oil and paints the Gulf Coast region black.
