Palin signs books, tests military rules

Sarah Palin brought her book-signing tour to North Carolina's Fort Bragg on Monday as thousands greeted the former Republican vice presidential candidate in a campaign-like gathering that tested military rules involving politicians.

The Department of Defense typically prohibits politicians from using installations as a platform, so Palin didn't give a speech and simply thanked soldiers individually. She was allowed to hold the event as a private citizen who was not campaigning, a Fort Bragg spokesman said.

Army officials initially feared the book signing might turn political and negative comments would be directed at President Barack Obama, so they barred media from attending.

The Army later relented and allowed coverage.
