Of note, her allegation regarding blackmailing a congresswoman was against Turkish agents whom the FBI was wiretapping, not the FBI themselves. In her deposition she specifically says

> [...] information was being collected for blackmail purposes, and her lesbian relationship, and they, the Turkish entities, wanted both congressional related favoritism from her, but also her husband was in a high position in the area in the state she was elected from, and these Turkish entities ran certain illegal operations, and they wanted her husband's help. But I don't know if she provided them with those. I left. I was terminated.

The penalties for lying under oath are usually anything but grave. Moreover: to punish her, the state has to prove that she knowingly lied. But I believe she believes what she's saying. That doesn't mean she's right.
