They're looking into recent sexual harassment claims made by Fox News guest Wendy Walsh, according to the report.
O'Reilly has been under investigation since April 1, when the New York Times reported about harassment allegations from five women against him, which totaled up to at least $13 million. Or is it possible that the famed Fox News talking-head might actually be taking a break from the "no-spin zone" for good?

O'Reilly has claimed that he settled the lawsuit to spare his children "the pain of a public ordeal" and he was targeted because he's a public figure. He said, "The worst part of my job is being a target for those who would harm me and my employer".
Sources also tell Sherman that there's a possibility that O'Reilly's Tuesday night show could be his last.

The host's apparent vacation comes after dozens of companies have pulled advertisements from his show, demonstrating a mass exodus from the airwaves in the wake of news of the accusations against O'Reilly. Meaning in March he had an average of nearly 15 minutes per episode of advertisement, and the other day they only had about four minutes worth of advertisements and ended up ending the show about eight minutes early because they had no ads.
