It is real, in the sense that this person, who we do not know the identity, gave this interview to Lin Wood. Now, I hope and expect that Wood verified this person's identity and did some background check regading the credibility of this person. We can not forget that in the past we had "fake whistleblowers" accusing Trump. Not that I do not believe what is said on the interview, but the whistleblower have to be credible to prevail in court.
