Conservative columnist and eleven-time New York Times best-selling author Ann Coulter is blasting Fox News.

“When it comes to immigration, Fox News is indistinguishable from George Soros,” the popular columnist wrote Thursday.

The “Rupert Murdoch enterprise,” Coulter writes, “is implacably pro-open borders, pro-amnesty and, consequently, anti-Trump.”

As Breitbart News has previously reported Rupert Murdoch, Fox News’ founder, is the co-chair of what is arguably one of the nation’s most powerful immigration lobbying firms, the Partnership for a New American Economy. Via his lobbying firm, Murdoch endorsed Marco Rubio’s Gang of Eight immigration bill, as well as Rubio’s 2015 immigration expansion bill, and has expressed his support for Rubio’s desire to grant citizenship– and, thereby, voting privileges and welfare access– to illegal aliens.

Coulter’s decision to speak out distinguishes her from the vast majority of conservative thinkers, who fear being iced-out of the so-called “conservative” corporate media.

“You won’t read about Fox News’s open-borders philosophy in National Review. You won’t hear about it on almost any ‘conservative’ webpages, magazines, radio shows, Twitter feeds or blogs,” Coulter writes.

Coulter says this is because “Fox News is the only game in town for conservative commentators and politicians. That’s why no other candidate would dare cross Fox… Viewers beware: The only ‘conservative’ opinion allowed on Fox News involves dissolving the nation’s borders.”

Coulter asserts that there is a real danger in continuing to perpetuate the charade that Fox News represents the “conservative” alternative: “One of the biggest problems facing the nation is that viewers think of Fox as the ‘conservative’ network. If NBC or ABC were this spiteful to Trump, everyone would see it for what it is: political bias. Your enemies can never hurt you; only your ‘friends’ can.”

For the “conservative” network to be pro-open borders is like secretly switching a diabetic’s insulin with sugar. The false labeling is lethal. Millions of people watch Fox News and think they’re getting the conservative antidote, when in fact the open borders corporatists have found a new way to package their open borders poison.

Coulter explains the network’s bias presents itself not so much in what the Fox News hosts say, but rather in what the network’s hosts do not say:

One of the hardest things to notice is what you’re not being told. Immigration is the issue shaking up this entire election and driving Trump to the top of the polls. But at Fox News, immigration is Issue No. 22 — after Iran, Iraq, Syria, Afghanistan, Russia, Russian President Vladimir Putin, Benghazi, Hillary Clinton’s emails, ISIS, ISIS, ISIS, Israeli Prime Minister Benjamin Netanyahu, the Export-Import Bank, entitlements reform, ISIS and everything else.

“Fox News’s bias is more insidious,” Coulter writes.

The hosts avoid stridently attacking Trump. You simply never hear from any pro-Trump guests — unless they’re completely ineffective. Immigration-opponents have been aggressively shut out — just as they were when Mr. Amnesty John McCain was running for president in 2008; when the Senate was debating Sen. Marco Rubio’s (R-Fla.) amnesty bill in 2013; and when congressional Republicans were trying to defund President Obama’s executive amnesty last year. Are you seeing the pattern?

Former George W. Bush speechwriter and senior editor of The Atlantic, David Frum, recently wrote of Coulter that “perhaps no single writer has had such immediate impact on presidential election since Harriet Beecher Stowe.” Frum explained that in Coulter’s latest book, Adios America, a tour de force on the critical issue of immigration, “Trump found the message that would convulse the Republican primary.”

Yet at the height of national intrigue following Trump’s announcement to abstain from the network’s debate, Fox News viewers tuning into Megyn Kelly’s program were presented with Michael Moore’s commentary on the GOP frontrunner’s decision– rather than Ann Coulter’s analysis.
