Fox News contributor and former VP candidate Sarah Palin took to Facebook to complain that her slated interviews on FNC were canceled today.

“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,” Palin wrote in a Facebook post.

Fox News responded in a statement from executive VP of programming Bill Shine:

“Our plans changed based on the fact that the RNC condensed the schedule of speeches from four nights to three,” Shine said. “We look forward to having Governor Palin back as soon as we can.”

Palin and FNC have not always seen eye to eye. On primary day in Alaska earlier this year, Palin gave an impromptu interview to a CNN reporter that was camped out in Wasilla.

Tonight, after her post, CNN anchor Piers Morgan tweeted:

If Fox don’t want you tonight @sarahpalinusa – come on my show. Be happy to talk about @senjohnmccain with you. #CNN
