ABC News producer Don Ennis has taken back his announcement that he's transitioning to Dawn Ennis.

Ennis, a 49-year-old parent of three, announced in a Facebook post in May that he was transgender and leaving his wife Wendy of 17 years.

In an office memo first obtained by, Ennis said that he suffered from a two-day bout of amnesia.

“I accuse my wife of playing some kind of cruel joke, dressing me up in a wig and bra and making fake ID's with the name 'Dawn' on it. Seriously,” Ennis wrote in the memo titled Not Reportable, Very Confirmed.

When he woke up from what he called a “transient global amnesia” Ennis said that he thought it was 1999 and “I was sure as hell that I was a man.”

“Fortunately, my memories of the last 14 years have since returned. But what did not return was my identity as Dawn.”

“I am writing to let you know I'm changing my name … to Don Ennis. That will be my name again, now and forever. And it appears I'm not transgender after all.”

He explained that “as recently as last Friday, I felt I was indeed a woman, in my mind, body and soul.”

“Even though I will not wear the wig or the makeup or the skirts again, I promise to remain a strong straight ally, a supporter of diversity and an advocate for equal rights and other LGBT issues including same-sex marriage.”

In explaining his transition to female last May, Ennis said that he suffered from an hormonal imbalance.
