What is also interesting is the supposed access to Top Secret info.  The vetting process for that sort of clearance is extensive.  With Manning's unsettled childhood and discipline problems earlier in his enlistment, a TS clearance would have been problematic and/or pulled.  More likely he did not have TS clearance and the info saying he did is incorrect.  But Wikipedia is not about truth, so no problem if this very small bit of information persists.
