MINNEAPOLIS — Humorist Garrison Keillor says he is in negotiations with Minnesota Public Radio after the radio network cut ties with the former “A Prairie Home Companion” host over unspecified allegations of inappropriate behavior.

Keillor wrote on his Facebook page Friday that a second day of mediation was held at a law firm in downtown Minneapolis, but he provided no details. He told The Associated Press on Monday that he could not discuss negotiations until they are finished. Another session is scheduled for Thursday, Keillor said.

Angie Andresen, a spokeswoman for MPR, said Monday the two sides “are talking about issues related to the transition of their business relationship.”

MPR announced in late November it was terminating its contracts with Keillor after learning of allegations of “inappropriate behavior” with a person who worked with him. Keillor told the Star Tribune that he had put his hand on a woman’s bare back as he tried to console her.
