I think that was Donald Rumsfeld you're thinking of...

“There are known knowns — there are things we know we know,” Rumsfeld said in February 2002, when asked for evidence that Saddam Hussein tried to supply weapons of mass destruction to terrorist groups. “We also know there are known unknowns — that is to say, we know there are some things we do not know. But there are also unknown unknowns, the ones we don’t know we don’t know.”
