Even if there was a 'mole', which I do not believe, how would any mole know about Classified Documents and even where they are kept? Doesn't that mean that the 'mole' must have reviewed the documents. So, is that classified information now compromised by the mole? Is the mole under investigation? Who are they? Who do they work for? Is the mole Russian, Iranian, or Chinese?
The 'mole' excuse only opens up a whole new situation. The mole, if true, is a wholly different thread to follow and investigate. Who is the mole working for? Is the mole still there?
