*(Via CNN) – NBC has apologized to Rep. Michele Bachmann after the house band for “Late Night with Jimmy Fallon” played an inappropriate song during her appearance on the show Monday, CNN confirmed Thursday.

Bachmann received a letter Wednesday from Doug Vaughan, NBC’s senior vice president for special programs and late night, that apologized for what happened and called the incident “not only unfortunate but also unacceptable,” said Alice Stewart, the Republican presidential hopeful’s spokeswoman.

According to Stewart, the letter also said the show’s band, which played the song “Lyin’ Ass Bitch” by Fishbone as Bachmann first appeared on stage, was “severely reprimanded.”

“She accepted the apology,” Stewart told CNN Thursday.

Bachmann also spoke to Fallon Wednesday and had a “nice conversation,” said Stewart, who described the late night host as “remorseful” and “a class act.”
