Sen. Ted Cruz, R-Texas, is frustrated by the Obama administration’s “stonewalling” on the Benghazi investigation – and he wants answers about the 2012 terrorist attack.

Speaking to Fox News’ Neil Cavuto yesterday, Cruz said: “We have four dead Americans. We have the first dead U.S. Ambassador killed in service since 1979. In the 19 months that have followed, we don’t have a single dead terrorist or a single terrorist apprehended, and what we have seen from the president and Senate Democrats has been stonewalling.”

Here are the four questions Cruz wants the Obama administration to answer:

Why did the State Department repeatedly refuse to provide additional security as was requested by personnel on the ground? Why did the United States not have military assets in place to protect American men and women on Sept. 11, 2012, when there was increased terrorist activity in the region? During the Benghazi attack, why didn’t the United States send in forces to protect the four men who lost their lives? In the 19 months that have followed, why has no one been apprehended, and no one been brought to justice?

Last year, Cruz introduced a Senate resolution calling for a joint select committee to investigate the Benghazi attacks. The House of Representatives is moving forward with its own select committee, which will be led by Rep. Trey Gowdy, R-S.C.

“The truth shouldn’t be partisan,” Cruz said. “Finding out what happened, finding out how we could have prevented it, and acting to actually apprehend these guys, should not be partisan.”
