A contentious "Rightwing Extremism" report that warned of military veterans as possible recruits for terrorist attacks against the U.S. was not authorized, has been withdrawn and is being rewritten, Homeland Security Secretary Janet Napolitano told Capitol Hill lawmakers.

"The wheels came off the wagon because the vetting process was not followed," Ms. Napolitano told the House Homeland Security Committee on Wednesday.

"The report is no longer out there," she said. "An employee sent it out without authorization."

The report was shared with state and local law enforcement officials nationwide via the department's internal Web site on April 7, angering Republican lawmakers and military veterans who said it unfairly stereotyped veterans.

Ms. Napolitano did not say when the report was taken off the "intel Web site" and all Homeland Security Department Web sites, but she said it is in the process of being "replaced or redone in a much more useful and much more precise fashion."
