“An entire year has gone by since these American heroes lost their lives serving our country and far too many question remain unanswered,” Cruz said on the Senate floor Wednesday. “We need a joint select committee to get these things.”

Cruz asked for unanimous consent to pass S.Res. 225, which would form the select committee, but Sen. Barbara BoxerBarbara BoxerFour more lawmakers say they’ve been sexually harassed by colleagues in Congress California Hispanics are the vanguard for a new political paradigm Trump riles Dems with pick for powerful EPA job MORE (D-Calif.) objected saying she put more faith in the Department of State accountability review board to get answers than a bunch of partisan politicians.

“I sense there is politics here,” Boxer said. “And I don’t think it’s right to inject politics into such a situation.”

Cruz and Roberts said the administration has failed to answer “simple” questions such as who told the military not to intervene in the attack and why a request for more security at the facility wasn’t fulfilled.

Roberts said it is also a “shame” that the international community still hasn’t arrested those involved in the attack despite the fact that the FBI has released photos of the terrorists.

“Justice has yet to be served,” Roberts said. “We simply want to know that this president and administration is working to seek justice for what has happened. … Yet it seems this president and administration is doing everything but seeking justice.”
