Neil deGrasse Tyson said Saturday that he will cooperate fully with an "impartial investigation" into recent allegations of sexual misconduct.

In a Facebook post, Tyson denied an accusation that he groped a woman and he denied that he made sexual advances toward a production assistant when he invited her to share wine and cheese at his home. He apologized for making the production assistant feel uncomfortable.

Fox and National Geographic are currently investigating the “Cosmos” host after new allegations of sexual misconduct.

In a story published Thursday in Patheos, a nondenominational, nonpartisan news service, two women accused Tyson of sexual misconduct. Dr. Katelyn N. Allers of Bucknell University claims that he groped her at an afterparty in 2009. The other woman, Ashley Watson, said that Tyson made inappropriate sexual advances and was forced to quit her job.

Tyson has not commented publicly and an email request for comment to his representative was not immediately returned.

Tchiya Amet claimed that Tyson had drugged and raped her in 1984. Patheos published that allegation on Nov. 8. She also made the claim in 2014 in a blog post.

Fox Broadcasting, which is a majority owner of National Geographic Television, issued a statement on the new allegations:

"We have only just become aware of the recent allegations regarding Neil deGrasse Tyson. We take these matters very seriously and we are reviewing the recent reports."

Tyson hosted "Cosmos,"a rebooted science documentary series, in 2014.

Besides numerous TV appearances, Tyson is also the director of the Hayden Planetarium at the American Museum of Natural History in New York City.
