His trip came as Fox News Channel's parent company weighs accusations that a woman's career was slowed when she spurned O'Reilly's advances.
Long-time Fox News personality Bill O'Reilly has been dumped by the network amid new revelations about lawsuits and cash settlements involving allegations of sexual harassment of women by O'Reilly.
"Bill O'Reilly has been fired from Fox News after years of multi-million-dollar sexual harassment suits", he said in his monologue. "I think he should do an interview with someone and not necessarily go to the favorable audience, to the safe space", he said.
Whether O'Reilly's absence from Fox will change the direction of the conservative movement, Jon Fleischman, conservative blogger from Orange County said mostly not.
"I will always look back on my time at Fox with great pride in the unprecedented success we achieved and with my deepest gratitude to all my dedicated viewers".
"We'd like to address questions about Bill O'Reilly's future at Fox News".
On his part, however, Bill O'Reilly continues to deny he has committed any sexual harassment act against another person.
That will be Tucker Carlson, whose show is moving to the 8 p.m. slot on Fox.
Up to four million viewers watched "The O'Reilly Factor" each evening, making it the most-watched cable TV program in 2016 and generating $446 million in ad revenues for Fox between 2014 and past year, according to a study carried out by Kantar Media.
Mr Burke, a former Fox News correspondent in Rome, denied having facilitated the tickets.
"The O'Reilly Factor" reportedly brought Fox more than $178 million in ad dollars in 2015 and $118.6 million in the first nine months of 2016. With a profit center gone, 21st Century Fox stock fell nearly 1 percent Wednesday in heavy trading.
Powers said she quit O'Reilly's show, but returned three years later.
In an interview with The New York Times, Fox News contributor Jehmu Greene claims that O'Reilly once made a comment about breaking her back while attorney Lisa Bloom announced that she is now representing Caroline Heldman. The company is making "a pretty big statement" to that effect by dropping O'Reilly, said Hall, the American University professor.
O'Reilly on Wednesday blamed his ouster on "unfounded claims" hours after Fox News announced his departure. "It speaks to a company that has recognized that the best business decision for them is to end their relationship with Bill O'Reilly". And right now, Fox is under the gun for this and also under a federal inquiry to see if it hid payments to women to try to keep it a secret - not only from the public but from shareholders, which could constitute a federal crime.
