Otherwise he would never talk to hed say, looking good, looking good, girl, when she got off the elevator. And probably most offensive to her was that he had a nickname for her, hot chocolate. Shes africanamerican. Fire bill oreilly reporter allegations against him have swirled for years. Perhaps the public protests, the advertiser exodus from the oreilly factor, finally forcing his employers hand. Today while oreilly shook hands with the pope in rome on his easter vacation, in new york, the networks Parent Company issued this statement. After a thorough and careful review of the allegations, the company and bill oreilly have agreed that bill oreilly will not be returning to the fox news channel. This evening oreilly released a statement that reads in part, it is tremendously disheartening that we part ways due to completely unfounded claims. That is the unfortunate reality many of us in the public eye must live with today. I will always look back on my time with fox with great no details on his exit. When his former boss chairman roger ailes was forced out after a Sexual Harassment scandal last year, he received a payout. Bill oreilly is arguably going to walk away with more than roger ailes did. Reporter a memo obtained by abc news reads in part, fox news has demonstrated again and again the strength of its talent bench. We have full confidence that the network will continue to be a powerhouse in cable news. Oreilly reportedly earned around 18 million a year at fox and brought in maybe five times that in ad revenue.

He brought it up first as soon as we sat down to dinner saying, wed like to make you a contributor. Reporter after dinner she says as we walked past the hostess stand at the restaurant, he turned right towards the bedrooms. I turned left towards the bar. And he caught up with me and said, no, no, come back to my suite. And i said, im sorry, i cant do that. And then he became hostile. All his charmingness went away. And he said the words you can forget all the Business Advice i gave you, youre on your own. Jimmy reporter that night, april 3rd, advertisers began to abandon oreillys show. Oreil like other prominent and controversial people im vulnerable to lawsuits from individuals who want me to pay them to avoid negative publicity. I think one of the reasons why my clients got so much love from the public in the last couple of weeks is because theyre not asking for any money. Reporter two days later, april 5th, even the president and avid fox news fan weighed in during an interview with the New York Times. I think he shouldnt have settled, personally. I think he shouldnt have settled. Because i know bill, bills a good person. I dont think bill would do anything wrong. Reporter the advertiser exodus trickle became a flood but oreillys ratings strong, even grew, averaging 3. 7 million every night last week. His viewers apparently untroubled by repeated reports oreilly was a serial offender. Accused of publicly accosting a producer. And a woman who says she taped the conversations. She sued. I came back because he agreed to not ever talk to me that way again. You claim he said the words to the effect, if any woman breathed a word id make her pay so dearly shed wish shed never been born this. Correct. We filed an extortion lawsuit. Reporter oreilly fired back this court and on the air. This is the single most evil thing i have ever experienced and ive seen a lot. These people picked the wrong guy. They can throw anything they want at me, ill take it. In the end, well see whos left standing. Reporter they settled and 13 years later the New York Times reported that oreilly personally paid her 9 million with both parties agreeing in that settlement that no wrongdoing whatsoever had occurred. The times also reporting in 2011, oreilly also personally settled with former fox business channel host Rebecca Gomez diamond for 1 million. Theres no question that there is a toxic culture at fox news of Sexual Harassment and retaliation. Reporter the problem was even bigger than oreilly. Fox exchairman former fox and friends age correspond Gretchen Carlson a 20 million settlement and apology. She claimed he sabotaged her career because she refused his sexual advances. I hope ive helped other women to win. Reporter ailes said, i will not allow my presence to become a distraction. Were talking here about a culture of Sexual Harassment. A culture, a hostile Work Environment that they knew they had a problem with. They knew it because it came from the top down. Reporter admit of last week, the tide began to turn. Against informatifoxs biggest. Oreilly took what was characterized as a preplanned vacation. We have a contest, guess where bills going, a full report when i return. Reporter he never did.

Officials say he was found hanging from a bed sheet with a bible verse john 3 16, a reference to eternal life through jesus, written across his forehead. Hernandez was serving a life sentence without the possibility of parole for the 2013 murder of odin lloyd, a semiprofessional Football Player who was dating the sister of hernandezs fiancee. The first thing you think of when you hear about the death of Aaron Hernandez is the death of odin lloyd and what his family had to go through with his death. Reporter only five days ago you find the defendant not guilty, guilty of murder in the first degree, guilty of murder in the Second Degree . Not guilty. Reporter he had just been acquitted in a separate murder case. After the jury read the verdict hernandez mouthed the words i love you to his fiancee. His cousin says the family is in pain tonight.

Lawyers for hernandez say they were actually exploring an appeal to the murder conviction for which he was serving the life sentence. Those who knew hernandez personally are expressing doubts as to whether he killed himself. We still think that theres no way that aaron would take his own life.

The patriots head coach, bill belichick, when asked during a recent cnbc interview what one word he would use to describe hernandez said tragedy. Heartbreaking. Yes. That would be another word. Reporter Aaron Hernandez was raised in a tough neighborhood in bristol, connecticut. When he was a teenager he suffered the grievous loss of his father with whom he was very close. I think any young child who loses a parent at such an impressionable age, particularly somebody that needed that guidance, its obviously a huge setback for that particular person. Reporter a few years later, hernandez rose to fame as an allamerican tight end at the university of florida, winning the 2009 national championship. Aaron allstate player, highly recruited. He had firstround talent. Reporter he eventually went on to play for the new England Patriots from 2010 to 2012.

He looked at his fiancee, who was absolutely in tears, and mouthed the words stay strong. Reporter it was a precipitous crash for a oncebeloved player. His cousin remembers better times. Whenever he came from practice or he came into town he would always ask every one of us if we needed anything, what can i do for you . He was a goodhearted person and not the meanspirited, evil that all these other people comment on or see him as.
