Famous American actor Jeffrey Tambor on Sunday said he may not return to "Transparent" after harassment allegations surfaced against him.

"I've already made clear my deep regret if any action of mine was ever misinterpreted by anyone as being aggressive, but the idea that I would deliberately harass anyone is simply and utterly untrue. Given the politicized atmosphere that seems to have afflicted our set, I don't see how I can return to 'Transparent,'" he said.
