The email reports that the Libyan thinks, “the people who would harm Rep. Issa are the same people who conducted the Benghazi attacks.”

Before Issa’s trip, Rep. Elijah Cummings, the ranking member of the House Committee on Oversight and Government Reform, issued a press release asking Issa to postpone his trip until he allows Democrats to join him.

“Although you claim that your investigation of the Benghazi attacks is bipartisan, your efforts to secretly plan an official trip to Libya — and then deliberately exclude Democrats from joining — is part of an unfortunate pattern of partisanship that undermines the credibility of this investigation,” Cummings wrote. “The problem with these actions is that they effectively deny Democratic Members the ability to effectively investigate this incident.”

Issa’s office responded on Thursday by lamenting the situation.
