'House of Cards' Creator Calls Kevin Spacey Sexual Misconduct Allegation 'Deeply Troubling'

"Anthony Rapp's story is deeply troubling. During the time I worked with Kevin Spacey on 'House of Cards,' I nighter witnessed nor was aware of any inappropriate behavior on set or off," Willimon said in a statement Monday. "That said, I take reports of such behavior seriously and this is no exception. I feel for Mr. Rapp and I support his courage."

Rapp told Buzzfeed in an article published Sunday that Spacey befriended him in the late '80s while they were both performing on Broadway. The actor recalled Spacey inviting him to a party at his apartment, putting him on his bed, climbing on top of him and trying to molest him before Rapp was able to push him off and leave.

Spacey responded to the allegation on Twitter Sunday by saying he doesn't remember the encounter, but he "owes him the sincerest apology for what would have been deeply inappropriate drunken behavior."

"I have a lot of respect and admiration for Anthony Rapp as an actor. I'm beyond horrified to hear his story. I honestly do not remember the encounter, it would have been over 30 years ago. But if I did behave then as he describes, I owe him the sincerest apology for what would have been deeply inappropriate drunken behavior, and I am sorry for the feelings he describes having carried with him all these years," Spacey said in a statement he released on Twitter Sunday night.

"This story has encouraged me to address other things about my life," the actor continued. "I know that there are stories out there about me and that some have been fueled by the fact that I have been so protective of my privacy. As those closest to me know, in my life I have had relationships with both men and women. I have loved and had romantic encounters with men throughout my life, and I choose now to live as a gay man. I want to deal with this honestly and openly and that starts with examining my own behavior."

Rapp's allegation against Spacey comes in wake of numerous allegations from women, including many famous actresses, that Harvey Weinstein sexually harassed or assaulted them throughout his decades of success in Hollywood. Weinstein has denied the accusations.

Willimon left "House of Cards" at the end of its fourth season in 2016.
