Days before Fox News's Republican presidential debate, front-runner Donald TrumpDonald TrumpEgypt’s death squads and America's deafening silence Glenn Beck: Trump 'doing a really good job of misdirection' New White House site touts successes of Trump’s first 100 days MORE is asking his supporters whether he should participate.
“Should I do the #GOPdebate,” Trump asked in a Twitter poll.
The tweet also included a link to an Instagram video in which he again accused Fox News host and debate moderator Megyn Kelly of being “biased.”
“Megyn Kelly is really biased against me,” Trump says in the short video. “She knows that. I know that. Everybody knows that. Do you really think she can be fair at a debate?”
Trump has increased his attacks against Kelly in recent days, threatening to skip the Thursday debate because he doesn’t think the host is capable of treating him “fairly.”
Fox News responded to Trump's poll later Tuesday.
"We learned from a secret back channel that the Ayatollah and Putin both intend to treat Donald Trump unfairly when they meet with him if he becomes president — a nefarious source tells us that Trump has his own secret plan to replace the Cabinet with his Twitter followers to see if he should even go to those meetings," the Fox News statement read.
Fox said Monday it was "surprised [Trump is] willing to show that much fear about being questioned by Megyn Kelly."
