(CNN) - Sarah Palin is slamming a new book about the 2008 presidential campaign that largely portrays the then-vice presidential candidate as wholly unprepared for the national stage and poorly versed in a range of pressing issues.
"These reporters were not any part of what I was doing there as the VP candidate," Palin said on Fox News Tuesday, her first appearance on the network as a paid contributor. "I don't know who they are. I haven't met these guys."
The book – "Game Change," written by political reporters Mark Halperin and John Heilemann - alleges McCain aides quickly grew troubled with Palin's lack of understanding on key issues, including the job of the Federal Reserve, the difference between North and South Korea, and the purpose of the war in Afghanistan.
"It's a bunch of BS from [McCain campaign manager Steve] Schmidt and those guys," Palin said. "It's pretty made up."
But the former Alaska governor did confirm one of the book's allegations: not knowing exactly who was behind the September 11, 2001 terrorist attacks and falsely believing former Iraqi President Saddam Hussein played a role.
"I did talk a lot to Steve Schmidt about the history of the war….could there have been any connection to Saddam [Hussein]," she said. "So I admit that I asked questions about it."
