The 71-year-old actress told Barbara Walters about the alleged incident in a 1991 interview.
Bette Midler is still waiting on an apology.
The 71-year-old actress took to Twitter on Thursday to call out Geraldo Rivera for allegedly groping her in the early '70s.
"Tomorrow is my birthday. I feel like this video was a gift from the universe to me," she tweeted alongside a clip from a 1991 interview with Barbara Walters. "Geraldo may have apologized for his tweets supporting Matt Lauer, but he has yet to apologize for this. #MeToo."
Rivera apologized on Wednesday afternoon after tweeting that sexual harassment allegations should me made in a timely fashion, require corroboration and that financial settlements push victims to be motivated by "more than justice."
In Midler's 1991 sit-down with Walters, the actress claimed that she was sexually assaulted by Rivera and his producer before an interview.
"Geraldo and his producer came to do an interview with me, in the '70s, in the early '70s, and this is when he was very, sort of, hot. And he and his producer left the crew in the other room, they pushed me into my bathroom, they broke two poppers and pushed them under my nose and proceeded to grope me," she alleged. "I did not offer myself up on the altar of Geraldo Rivera. He was unseemly. His behavior was unseemly. My friend says, 'Oh, what a charmer! Of course you slept with him after that!'"
"Wow. Let's go on to other things, shall we?" Walters replied.
