Senator John McCain (R-AZ) says he might seek a subpoena to gain the information he wants about the attack in Niger.
"It may require a subpoena," he told reporters on Thursday. "I did have a good conversation with Gen. McMcMaster and they said they would be briefing us. We've had a long friendship and we'll hopefully get all the details."
"We did not know about Niger until it came out in the paper. We need to have a process of communications, which I've had with other administrations, of exchanging information and knowledge," McCain also said.
