The war of words on the right continues to escalate, with radio host Mark Levin becoming the latest Fox News figure to attack Fox political analyst Karl Rove. In a February 8 post on his Facebook page, Levin accused Rove of lying about conservative Rep. Steve King (R-IA). Earlier in the week on his radio show, Levin claimed Rove is “despised by the grassroots” and said Rove's name and new political group “are poison in conservative and Republican circles in many respects.”

Rove has recently been at the center of a conservative firestorm over the announcement of his new group, Conservative Victory Project, which the New York Times explains will work “to recruit seasoned candidates and protect Senate incumbents from challenges by far-right conservatives and Tea Party enthusiasts.”

Levin -- a frequent Fox News guest who has agreed to make regular appearances on Sean Hannity's Fox show -- wrote on his Facebook page that Rove “flat out lied” during an appearance on Sean Hannity's radio show. According to Levin, Rove told Hannity that Rep. Steve King (R-IA) had “endorse[d]” controversial comments about rape made by defeated Missouri senatorial candidate Todd Akin. Levin added, “This is the kind of sleaziness conservatives are fed up with. And Rove went on national radio and smeared King with this lie.”

King, who is reportedly considering running for a Senate seat in Iowa, has been identified as the type of conservative Rove's organization would likely target. Steven Law, president of American Crossroads, the super PAC co-founded by Rove that created the Conservative Victory Project, has expressed concern about King's history of extreme comments, which Law labeled his “Todd Akin problem.”

Levin has also targeted Rove on his radio show. On February 7, Levin declared that Rove is “despised by the grassroots,” mocked his “stupid little third-grade whiteboard,” then brought “my buddy” King on the show and said: “Steve King and all you conservatives out there who are thinking about running in these primaries and so forth -- your best commercial is going to be that your opponent is funded by Karl Rove. I'm serious, Steve King -- I think Karl Rove's name, I think his organization are poison in conservative and Republican circles in many respects.” Levin added, “Bring it on, Karl baby. Bring it on, doughboy. Bring on your little whiteboard. We're ready.” During the same show, Levin also labeled Rove a “propagandist.”

Levin follows Erick Erickson, Liz Cheney, and Mike Huckabee as Fox contributors and regular guests who have joined numerous conservative pundits in criticizing Rove.
