Fox News contributor Karl Rove denied a negative story appearing in a new book from presidential candidate and Sen. Ted Cruz (R-TX), but Cruz has now produced an email from Rove that appears to back his version of events. This is just the latest exchange in an ongoing fight between Rove and the conservative movement.

In his new book A Time For Truth: Reigniting the Promise of America, Cruz wrote that Rove tried to bury a donation President George H.W. Bush made to Cruz for his 2009 Texas attorney general campaign.

Cruz explained that Rove was “in the process of helping raise money for the George W. Bush presidential library in Dallas” while “Texas donors were giving the Bushes tens of millions, including major donors who were supporting the Dallas state rep who wanted to run for attorney general.” According to Cruz, those donors started “berating” Rove.

Rove denied the allegation, writing, “When Mr. Cruz and I talked in 2009, I was not raising money for the Bush Library,” adding, “nor were any library donors 'berating' me.”

Cruz's presidential campaign responded by releasing the details of the email exchange he had with Rove. In the email, Rove allegedly said, "[T]he distress you mention is not mine or 43 -- it is the people raising money for the library who are also [then-Texas Rep. Dan] Branch fans and will not understand why one part of the Bush family is for not-the-guy while they are raising money big bucks for library."

In the release, Cruz describes Rove's response to the story as “a straight-out falsehood” and an example of “why people are so cynical about politics, because too many people are willing to lie.”

Rove's chief of staff told The Texas Tribune that Rove doesn't have a record or any recollection of the email.

Conservative radio host Mark Levin linked to the release on his Facebook page with the comment, “Ted Cruz sets the record straight with sleazy Karl Rove.”

This is not Rove's first fight with the conservative movement.

In 2013, when Rove announced plans for “the Conservative Victory Project,” an attempt to protect incumbent Republicans from Tea Party challengers, many in the movement condemned him.

Former Arkansas Governor Mike Huckabee said the group was “repulsive” and guilty of “fratricide.” Levin described Rove as a “propagandist” who is “despised” by the conservative grassroots. Donald Trump called Rove “a total loser” and said “money given to him might as well be thrown down the drain.” In a recent Fox appearance, Rove said Republicans should ignore Trump, who is “not a serious candidate” for president.

Michelle Malkin declared “war” against “Rove and his big government band of elites.”

A year later, Media Research Center's Brent Bozell said Rove “has never cared about conservatism and has spent his entire career opposing any Republican who might be successful in promoting or implementing a conservative agenda.” He also urged conservatives to “make sure Karl Rove no longer has any influence on their party.”

After Rove bemoaned the nomination of Senate candidate Christine O'Donnell in Delaware in 2010 (she would go on to lose the general election), conservatives pounced. Malkin described him as an “effete sore loser,” Fox contributor Erick Erickson said he was “in full-on meltdown,” while Rush Limbaugh said, “I've never heard Karl so animated against a Democrat as he was against Christine O'Donnell.”

In 2010, Rove said that Sarah Palin appearing on a reality show would not help her in convincing voters that she was a viable presidential candidate. Palin said his comments were “quite negative and unnecessary,” and Rove responded by saying he was “sorry if she took offense” but “I hope she's got a thicker skin than that.” He later went on to do a negative impersonation of Palin during an interview with New York magazine:

When I bring up his statements about Palin during our interview, Rove says only that he wished he'd made his comments on Fox News instead--before going into a withering impersonation of Palin, recalling a scene from her TV show in which she's fishing.

“Did you see that?” he says, adopting a high, sniveling Palin accent: " 'Holy crap! That fish hit my thigh! It hurts!' "

“How does that make us comfortable seeing her in the Oval Office?” he asks, disgusted. “You know--'Holy crap, Putin said something ugly!' ”
