A Senate Republican demanded answers on Saturday as to why U.S. officials can't get into Benghazi to investigate the Sept. 11 attack on the consulate.
“As of this morning, reports indicate that our well-trained FBI agents still have not been able to get into Benghazi to investigate," he wrote.
"What has changed in Libya in such a short time that even FBI agents, our most elite investigative personnel, cannot safely enter the city? What has led to such a precipitous decline?”
The Senate Foreign Relations Committee member questioned why there was a lack of security for the ambassador and his staff and why the FBI is still unable to get into Benghazi.
“An unwillingness to provide answers and the inaccuracy of the limited information we have received to date has undermined the credibility of the administration," he wrote.
"To avoid further damage, I ask that you please personally respond with substantive answers very quickly.”
