(CNN) - Sarah Palin posted a cryptic message on Facebook Wednesday night, saying the Fox News Channel had cut her appearances for the evening.
"I'm sorry Fox cancelled all my scheduled interviews tonight because I sure wanted to take the opportunity on the air to highlight Senator John McCain's positive contributions to America, to honor him, and to reflect on what a biased media unfairly put him through four years ago tonight," she wrote.

Palin, who served as McCain's 2008 vice presidential nominee, did not explain why Fox had scratched her off their rundown.
The former governor has been a pundit on the channel since early 2010, less than a year after she stepped down from her post as governor of Alaska.
Reports of tension between the conservative firebrand and the network emerged in November, when New York Magazine reported the network's president, Roger Ailes, was furious that Palin had announced her decision against running for president on another media outlet.
Palin first made her decision public on a conservative radio show hosted by Mark Levin, then confirmed her announcement in a Fox appearance on Greta van Susteren's show that night. While Ailes reportedly considered pulling her million dollar contract, Palin continued to appear on the Fox News Channel and Fox Business Network.
As to what prompted Wednesday night's shuffle, Palin left it a mystery, writing only about her former running mate. Sen. John McCain is set to deliver remarks at the Republican National Convention in the 8 p.m. ET hour. The Arizona senator also turned 76 on Wednesday.
"Granted, our honored and esteemed war hero has gone through much more than the liberal media can ever do to him in their efforts to harm this patriot. I look forward to hearing his words to his fellow Americans tonight more than any of the other convention speeches. God bless John McCain," she wrote. "Thank you for everything. And happy birthday, my friend."
Fox did not immediately return a request for comment.
The liberal media harmed John McCain? ... You mean the way the conservative pundits honored John Kerry's military service?? (even worse when compared to Bushy Jr)
HA! PALIN IS OBSESSED WITH 4 YEARS AGO AND HER 'VICTIM' STATUS! All she can talk about is BLAMING OTHERS!
Wow, she is as ego-centric as Donal Trump, as unaccomplished as Paris Hilton and as obsessed as Sheriff Joe.
Snooki Palin just won't take a hint. Get lost.
Perhaps FOX is finally waking up. That would be a miracle, but just perhaps???????
Too stupid to make it on Fox. That is really pathetic. Good riddance.
She might have to get a real job!!
Fox News, please give Sarah more air time. The presidential election is too close to call right now. We really need her to vigorously support Romney and bash Obama. I am concerned that without her participation, Obama could lose the election.
Starting with her ta tas anyone have a picture of her before and after. I guess money can buy plastic surgery but not a brain!
How will anyone ever live with her wisdom and insight? She served her purpose buy delivering the tea partyto the GOP and now she is no longer needed.
Maybe they will cancel the whole republican party.
why is anything this fame hound says newsworthy? Enough already. Ignore the moronic rhetoric from this sad excuse of a politician and maybe she'll mercifully go away. Forever
Oh dear, how quickly the reign ends.
Take a hint Sarah. You got rich off your extended 15 minutes, but now it's time to say bye bye, "you betcha".
What an annoying woman!! Why does she think anyone cares what she has to say on any topic!! After watching "Undefeated" it is clear she is dumber than a stump!!! Good god gal, please just fade away
She's delusional. They really got it right in "Game Change", she's oblivious to her ignorance, thinks she really is all that, and doesn't realize a huge majority of people don't take her seriosly. I hope the media does her and all of us a favor and lets her disappear. I guess Fox has now joined the ranks of her "lame stream media".
The twit speaks. Sarah, everytime you whine abouut the media you only make yourself look even more pathetic, if that's possible. You were unprepared, you can learn from it or you can act like a child and blame everyone else. The fault was your's and your's alone. It's a shame you don't have some character to go along with that big mouth.
"on what a biased media put him through, she said"... as a 'journalist' on a network she considers to be unbiased. Sarah, your lack of self-awareness remains hilarious. Those who eat up her every word, more sad and pathetic than hilarious unfortunately.
Hopefully this will be the end of Sara Palin.
