That e-mail was referenced by Sergeant McCabe himself:

I again remarked that I was concerned and seriously concerned that I was never contacted or interviewed." [This is to Assistant Commissioner O'Mahony] I informed the Assistant Commissioner that I had seen tens of thousands of ...terminations on PULSE and I hoped his report would reflect this. Alarmingly, he then asked me if I wanted to speak to someone on his investigation team. I ended our call having expressed concern about him not interviewing me.

He was invited to meet a member of the investigation team.
