SAN FRANCISCO (AP) — The words “I am truly sorry” have not been uttered often in the #MeToo era. So when soprano Luz del Alba Rubio woke up Tuesday to see an apology from opera superstar Placido Domingo, she was in shock.

“I felt like we have conquered Goliath. Now we don’t have to be scared to speak out,” said Rubio, who stepped forward Tuesday to add her voice to the women accusing the legendary tenor of sexual harassment and abuse of power.

Domingo’s statement came after the U.S. union that represents much of the opera world said its investigators found the opera star and former general director at Washington National Opera and Los Angeles Opera had behaved inappropriately over the course of two decades.

“I have taken time over the last several months to reflect on the allegations that various colleagues of mine have made against me,” Domingo said in a statement issued in connection with the findings. “I respect that these women finally felt comfortable enough to speak out, and I want them to know that I am truly sorry for the hurt that I caused them. I accept full responsibility for my actions, and I have grown from this experience.”
