I watched the interview with her, tough to glean much from it except I learned about the intelligence process behind the scenes. The only real method would be as Rand Paul suggested, that she testify in front of Congress.
Also, the leak or whistleblower has to confront her and provide the evidence that she shared spreadsheet of unmasked names about the Trump campaign team. This is the best way to provide transparency and accountability as Americans expect.
As an aside, I watched a few more minutes of MSNBC and they appear frighteningly more balanced than CNN is now...what's going on? I'm sure my opinion would change if I watched the Rachel Maddow show hah, I've seen her in meltdown mode and it's as unprofessional and embarrassing as anything you might see on TV.
