Profile: Bernard Kerik

— -- A lifetime of policing has prepared Bernard Kerik to be secretary of the Department of Homeland Security.

Kerik first rose to national prominence following the Sept. 11 terrorist attacks when he was New York City's police commissioner. He managed the department's response to the attacks and was a steady -- if stoic -- presence by Rudolph Giuliani's side as the then-mayor and President Bush tried to reassure New Yorkers and the nation following the worst terrorist attack on U.S. soil.

But Kerik brings more than his tenure as leader of the NYPD as Bush's nominee to succeed Tom Ridge. After leaving the police department, he joined Giuliani Partners, where he was a security consultant. In 2003, he was tapped by the Bush administration to be Iraq's interim minister of the interior and helped rebuild and train the country's police force following the U.S.-led coalition's overthrow of Saddam Hussein. While in Iraq, Kerik was dubbed the "Baghdad Terminator" after he dismissed a reinstated Iraqi official who turned out to be a member of Saddam's Baath Party.
