House Oversight Committee Chairman Darrell Issa (R-CA) compromised the identities of several Libyans working with the U.S. government and placed their lives in danger when he released reams of State Department communications Friday, according to Obama administration officials.

Issa posted 166 pages of sensitive but unclassified State Department communications related to Libya on the committee’s website afternoon as part of his effort to investigate security failures and expose contradictions in the administration’s statements regarding the Sept. 11 attack on the U.S. mission in Benghazi that resulted in the death of Amb. Christopher Stevens and three other Americans. …

But Issa didn’t bother to retract the names of Libyan civilians and local leaders mentioned in the cables, and just as with the WikiLeaks dump of State Department cables last year, the administration says that Issa has done damage to U.S. efforts to work with those Libyans and exposed them to physical danger from the very groups that had an interest in attacking the U.S. consulate.
