They issued the statement after Burr told reporters on Wednesday morning that he had asked his staff to review the debate transcript for references Cruz made to a National Security Agency (NSA) surveillance program during a back-and-forth with Sen. Marco RubioMarco Antonio RubioRyan pledges 'entitlement reform' in 2018 Richard Gere welcomes lawmakers' words of support for Tibet Dem lawmaker gives McConnell's tax reform op-ed a failing grade MORE (R-Fla.).
 
"The question had been raised; therefore, I asked them to look at it," he said. "Any time you deal with numbers ... the question is, is that classified or not, or is there an open source reference to it."
 
During the exchange with Cruz, Rubio brought up the subject of classified material. 
 
"Let me be very careful when answering this, because I don't think national television in front of 15 million people is the place to discuss classified information," Rubio said at the debate. "So let me just be very clear. There is nothing that we are allowed to do under this bill that we could not do before."
 
Cruz, during the debate, said that the NSA's recently revamped program — which collected data on U.S. phone calls in bulk — applied to "20 or 30 percent of phone numbers" while the new version covers roughly 100 percent.
 
Becca Glover Watkins, Burr's communications director, suggested on social media that Cruz might have said something he shouldn't have, though she didn't specifically reference his comments. 
 
But Cruz's campaign quickly said that the Texas Republican hadn't said anything that wasn't already reported, including in a 2014 Washington Post article. 
 
The Post reported at the time that the NSA "is collecting less than 30 percent of all Americans' call records." 
 
Cruz isn't the first senator to discuss the amount of information collected under the NSA's old program.
