The Daily Caller is one of the most freewheeling conservative outlets in online media. Its reporters have leveled unsubstantiated allegations of prostitution against Senator Bob Menendez, falsely accused a New York Times reporter of posing nude for Playgirl, and even questioned the race of a black Washington Post reporter. These stories raise an interesting question: What wouldn’t the Daily Caller publish? Today one of its contributors learned the answer: Absolutely anything critical of Fox News.

Last night, the anti-immigration blogger Mickey Kaus published a post criticizing Fox News for focusing on stories about ISIS over stories about several political disputes concerning federal immigration policy. “Fox didn’t editorialize in favor of Obama,” Kaus wrote. “It just covered other issues. This is a proven pro-amnesty posture, pioneered in the spring of 2013 when the ‘Gang of 8’ amnesty bill snuck through the Senate while conservatives were distracted by a seeming trifecta of Obama scandals (IRS/Benghazi/seizing AP reporters’ phone records).” Kaus went on to blame Fox chief Roger Ailes, rather than low-level producers, for this editorial decision. Kaus often brands himself as a liberal on certain issues (such as healthcare policy), but in this case he was attacking Fox from the channel’s right.

A few hours later, according to Politico, Daily Caller editor-in-chief Tucker Carlson deleted Kaus’ post from the site. Not because Kaus drew from the right’s well-known hostility to immigrants, but because Kaus had attacked Fox News, where Carlson anchors Fox & Friends Weekend (and frequently appears on shows like Outnumbered). Here’s how Kaus put it to Politico’s Dylan Byers:

“It’s pretty simple,” Kaus said in an interview, “I wrote a piece attacking Fox for not being the opposition on immigration and amnesty—for filling up the airwaves with reports on ISIS and terrorism, and not fulfilling their responsibility of being the opposition on amnesty and immigration.... I posted it at 6:30 in the morning. When I got up, Tucker had taken it down. He said, ‘We can’t trash Fox on the site. I work there.’”

Shortly thereafter, Kaus quit the Daily Caller. He also left Politico with an observation that is almost never voiced within conservative media (yet is deeply obvious to anyone outside of it): “It’s a larger problem on the right: Everybody is scared of Fox.”
