(CNN) Magician Penn Jillette, one half of the duo Penn &Teller, claims he heard President Donald Trump say "racially insensitive" remarks during his time appearing on the reality competition show, "The Celebrity Apprentice."

Jillette stopped short of confirming the details of Trump's alleged comments, but his assertion comes at a time of renewed discussion about whether Trump purportedly said the N-word, a racial epithet, during production of the reality TV series.

"He would say racially insensitive things that made me uncomfortable," Jillette told Vulture in an interview. "I don't think he ever said anything in that room like 'African Americans are inferior' or anything about rape or grabbing women, but of those two hours every other day in a room with him, every ten minutes was fingernails on chalkboard."

Asked if tapes of Trump making those comments exist, Jillette said, "Yeah, I was in the room."

Jillette gave one example of Trump speaking about women in a demeaning way, but declined to provide more specifics.
