Pakistan insists bin Laden eluded intel

>>> and now more questions here. first, in a town loaded with pakistani military , cadets, active duty, and retired, how plausible is it no one knew bin laden was living in that big house , and how are things between the two countries now that the u.s. has launched a raid inside pakistan without advance warning or permission apparently? our chief foreign affairs correspondent andrea mitchell in our d.c. newsroom with a look at both of those questions. andrea, good evening.

>> good evening, brian. those are the questions. relations with pakistan had already been on the down slide, especially after that prolonged arrest and jailing of a cia contractor recently. but now there is an even worse breach. and frankly, i cannot find a senior official in the u.s. government who is not deeply suspicious about the surprising circumstances of bin laden 's location in what was essentially a military enclave, right down the road from pakistan 's military academy . intelligence chair dianne feinstein told me that she is going to be asking those very questions starting tomorrow morning at a closed hearing with intelligence officials. essentially, what did pakistan know, when did they know it? and she's asking were they warned off by higher-ups in the government from even checking out the compound? today pakistan amped up its criticism of the raid. after initially saying that bin laden 's death illustrates international resolve to eliminate terrorism, now pakistan 's government is warning against what they call an unauthorized american raid that should not serve as a precedent for the future. pakistan 's ambassador to the u.s. told me today that they are asking themselves whether they had an intelligence failure , but he insists that pakistan 's government was not involved in hiding bin laden . even though he was hiding in plain view . brian.

>> of course no guarantee we'll ever know either way. andrea mitchell in our washington newsroom tonight. andrea, thanks.
