On April 24, 2006, Hot Air, a "conservative Internet broadcast network", went into operation, with Malkin as founder/CEO. The site's staff at launch included Allahpundit and Bryan Preston. Preston was replaced by Ed Morrissey on February 25, 2008. In February 2010, Hotair.com was bought by Salem Communications and is no longer administered by Malkin.
Malkin was among the first of several bloggers who questioned the credibility and even the existence of Iraqi police Captain "Jamil Hussein" who had been used as a source by the Associated Press in over 60 stories about the Iraq war. The controversy started in November 2006 when the AP reported that six Iraqis had been burned alive as they left a mosque and that four mosques had been destroyed, citing Hussein as one of its sources. In January 2007, Malkin visited Baghdad, and stated, "the Iraqi Ministry of Interior says disputed Associated Press source Jamil Hussein does exist. At least one story he told the AP just doesn't check out: The Sunni mosques that as Hussein claimed and AP reported as 'destroyed,' 'torched' and 'burned and blown up' are all still standing. So the credibility of every AP story relying on Jamil Hussein remains dubious." Malkin has since issued a correction for her denial of Hussein's existence, "I relayed information from multiple sources—CPATT, Centcom, and two other military sources on the ground in Iraq—that the Associated Press's disputed source, Jamil Hussein, could not be found." [...] "I regret the error," but still contested AP claims of destroyed mosques and civilians burned alive.
In April 2006, Students Against War (SAW), a campus group at University of California, Santa Cruz, staged a protest against the presence of military recruiters on campus, and sent out a press release containing contact details (names, phone numbers and e-mail addresses) of three student leaders for use by reporters. Malkin included these contact details in a blog column entitled "Seditious Santa Cruz vs. America". Malkin claimed the contact information was originally taken from SAW's own website, but that later SAW had removed it and had "wiped" the "cached version". The students asked Malkin to remove the contact details from her blog, but Malkin reposted them several times writing in her blog: "I am leaving it up. If you are contacting them, I do not condone death threats or foul language. As for SAW, my message is this: You are responsible for your individual actions. Other individuals are responsible for theirs. Grow up and take responsibility."
Another controversy involving private addresses began on July 1, 2006, when Malkin and other bloggers commented on a New York Times Travel section article that had featured the town where Vice President Dick Cheney and Secretary of Defense Donald Rumsfeld owned summer homes. The article included a picture of Rumsfeld's long tree-lined driveway that showed a birdhouse and small portion of the housefront. Malkin declared that this story was part of "a concerted, organized effort to dig up and publicize the private home information of prominent conservatives in the media and blogosphere to intimidate them." The photos of Rumsfeld's house were taken with Rumsfeld's permission.
In 2006, Malkin gave a lecture at her alma mater, Oberlin College, discussing racism, among other topics. She denied allegations that she had been insensitive to the "plight of minorities", listing several racial epithets that had been used against her, and by relating a lesson she learned from her mother for which she is "eternally grateful". When in kindergarten, Malkin went home in tears one day because her classmates had called her a racist name. But her mother comforted Michelle by telling her that everyone has prejudices.
