Geraldo Rivera apologizes to Bette Midler for alleged groping incident

He also noted his recollection of the incident differed from Midler's.

"Although I recall the time @BetteMidler has alluded to much differently than she, that does not change the fact that she has a right to speak out & demand an apology from me, for in the very least, publicly embarrassing her all those years ago. Bette, I apologize," He wrote Friday.

Midler was referring to Rivera's other mea culpa, this time after defending Lauer, even calling him a "great guy" following his termination from NBC earlier this week for what his former network called "inappropriate sexual behavior." Midler also added a #MeToo hashtag, a symbol of speaking out on social media against sexual harassment or assault.

"Poppers" is slang for the recreational drug alkyl nitrite.

"Grope?" Walters asks, looking surprised. Midler responds, "Groped me. I did not offer myself up on the altar of Geraldo Rivera. He was ... he was unseemly."

A representative for Midler told ABC News that she had no further comment beyond her tweet. Before his tweet, Rivera's representative did not immediately respond to a request for comment from ABC News.

In a review of Rivera's 1991 memoir, "Exposing Myself," The Washington Post pulled a line from the book, in which he wrote about his version of the alleged incident, "We were in the bathroom, preparing for the interview, and at some point I put my hands on her breasts."

In the tweet that caught Midler's attention, which he would later "humbly apologize" for, Rivera wrote, "Sad about @MLauer great guy, highly skilled & empathetic w guests & a real gentleman to my family & me. News is a flirty business & it seems like current epidemic of #SexHarassmentAllegations may be criminalizing courtship & conflating it w predation."
