Homeland Security Chief Janet Napolitano apologized to veterans angry over the department's report that returning vets could be recruited by right-wing extremist groups. "I think it is important for all of us to remember that Americans are not the enemy. The terrorists are," the head of the American Legion wrote in a letter to Napolitano. On CNN this morning, Napolitano responded: "I know that some veterans groups were offended by the fact that veterans were mentioned in this assessment, so I apologize for that offense. It was certainly not intended," she said. "The return of military veterans facing significant challenges reintegrating into their communities could lead to the potential emergence of terrorist groups or lone-wolf extremists capable of carrying out violent attacks," the report said, citing Timothy McVeigh, the Gulf War vet who bombed the federal building in Oklahoma City.
