Victoria Toensing, a former Justice Department official and one-time Republican counsel to the Senate Intelligence Committee, told Fox News earlier this week that a State Department employee she represented was threatened by superiors if he cooperated with the House Oversight Committee’s investigation into Benghazi.
White House press secretary Jay Carney said Wednesday he was “unaware of any agency blocking an employee who would like to appear before Congress to provide information related to Benghazi.”
Carney added that "everyone who had something to say was welcome to provide information" during the official investigation into the attack.
"Both the State Department and Department of Defense have made clear that they are not aware of any requests for a security clearance for a private attorney," Carney said.
Asked about issue at his press conference Tuesday, Obama he was “not familiar” with anyone being blocked.
“I'm not familiar with this notion that anybody's been blocked from testifying,” Obama said. “What I've been very clear about from the start is that our job with respect to Benghazi has been to find out exactly what happened, to make sure that U.S. embassies, not just in the Middle East, are safe and secure, and to bring those who carried it out to justice.”
Rep. Darrell Issa (R-Calif.), chairman of the House Oversight Committee, said Wednesday that eyewitnesses will be testifying before his committee next week.
