Sen. Ted Cruz, R-Texas, panned as cheap talk former Secretary of State Hillary Clinton's statement that her "biggest regret" is the Sept 11, 2012, Benghazi terror attack.

"If she really was sorry, then she would stand up and join me and 22 other senators calling for a joint select committee in Congress to investigate why our facilities in Benghazi were not secure, why we didn't respond to the reports of terrorist activities, why we didn't have military assets in place to protect our brave men who were serving there, and and why nobody has been held accountable — not a single person's been fired at the Department of State, and none of the terrorists who attacked us over a year ago have been brought to justice," Cruz said on Fox News on Monday afternoon.

"If she was really sorry — talk's cheap; she needs to stand up and demand action," he concluded.

Clinton and President Obama's team have relied on the Accountability Review Board's report on the attack, which did not call for the removal of top State Department officials, as a sufficient investigation.

The Daily Beast found one State Department employee who was punished over Benghazi. "Following the attack in Benghazi, Libya, senior State Department officials close to Hillary Clinton ordered the removal of a midlevel official who had no role in security decisions and has never been told the charges against him," Josh Rogin wrote last May. "He is now accusing Clinton's team of scapegoating him for the failures that led to the death of four Americans last year."

Rep. Frank Wolf, R-Va., reiterated his request that House Speaker John Boehner, R-Ohio, appoint a House select committee to investigate the attack.

“You know me well enough to know that my persistence in pursuing answers isn't about politics or a vendetta, it's about the Legislative Branch conducting its most basic responsibility: strong oversight,” Wolf wrote in a letter to Boehner. “To date, we can't honestly say we've fulfilled this constitutional responsibility with regard to Benghazi.”

Senate Majority Leader Harry Reid, D-Nev., has blocked Senate participation in such an investigation.
