John Cusack In Twitter War With "Satanic Death Cult" Fox News

Left-leaning actor takes cable channel to task for its demagoguing of the so-called Ground Zero mosque

In light of this week's Discovery Networks hostage standoff which ended with police killing the gunman, perhaps John Cusack might want to tone it down a bit.

The 44-year-old actor found himself in a war of words with Fox News after he issued a tart reply on his Twitter page to a fan's question about whether he's for or against the so-called Ground Zero mosque.

"I AM FOR A SATANIC DEATH CULT CENTER AT FOX NEWS HQ AND OUTSIDE THE OFFICES [OF] DICK ARMEY AND NEWT GINGRICH-and all the GOP WELFARE FREAKS," Cusack wrote in a sarcastic all-caps tweet Sunday evening to his 200,000-plus followers.

That didn't go over so well with the touchy right-wing network, which blasted the Say Anything star and self-described progressive, accusing him of "making threats."

Fox News columnist Joe Piazza on Tuesday quoted Dr. Carole Lieberman, a Beverly Hills psychiatrist, who said that Cusack's "provocative tweets could easily incite a rabid fan to commit violent acts against Fox News Headquarters and others he names."

"Fans could not only be influenced because of their devotion to Cusack, the man, but also because of their love for one of the characters he plays," she said.

It would also be nice to know what Dr. Lieberman thinks of Fox News months-long campaign of incitement against the proposed Islamic community center, but no comment was forthcoming on that topic.

For his part, Cusack remained unapologetic.

"Thanks for all the fact-challenged souls who don't like opinions—you may not like me but never had one person debate the facts," he tweeted later.

The thesp further vented his feelings on the mosque issue, writing in a follow up post that his previous Tweet was an "absurd over the top joke" made "after the 900th time I was asked about ground zero center-they can't even print it."

Cusack's rep has yet to comment on the dust up. 

The A-lister meanwhile just signed on to play Edgar Allen Poe in the fictional drama The Raven which, per the Hollywood Reporter, finds the famed writer trying to track down a serial killer who takes his poems, ahem, a bit too seriously.
