Democratic presidential candidate Hillary ClintonHillary Diane Rodham ClintonJustice to provide access to Comey memos to GOP lawmakers Justice Dept inspector asks US attorney to consider criminal charges for McCabe: reports 'Homeland' to drop Trump allegories in next season MORE said on Sunday it's good news that a former State Department staffer was granted immunity from prosecution in the criminal investigation into her email server.

"It's a security review. I'm delighted that he has agreed to cooperate, as everyone else has," she said on CBS's "Face The Nation."

"And I think that we'll be moving toward a resolution."

Last week, the Justice Department granted immunity to a State Department employee who helped build Clinton's private email server.

Clinton said on Sunday she thinks that the issue is getting "closer and closer" to being wrapped up.

"I also know that there were reports today about the hundreds of officials and the thousand emails that they were sending back and forth that have been looked at and classified retroactively," she said.

"This really raises serious questions about this whole process. 

"So I'm hoping that, you know, we'll get through this and then everybody can take a hard look at the interagency disputes and the arguments over retroactive classification," she said.

She added that she is the one who asked her emails be made public, touting herself as "more transparent than anybody I can think of in public life."

"But it's also true that when something is made public, everybody from across the government gets to weigh in, and that's what's happening here," she said.

"And we need to get it sorted out and then take action from there."
