NEW YORK - Fifteen years after 9/11, some victims' families feel they still haven't been told the whole truth about who was responsible.

They want to know what's in 28 classified pages that describe investigative leads about "specific sources of foreign support" for the terrorists. Lawmakers who have read the document say it sheds light on possible Saudi connections.

Lorie Van Auken lost her husband. She says the families "want to stop guessing."

They soon may. President Barack Obama has hinted that at least portions of the document may be released shortly.

Some 9/11 families expect the pages' contents will help their effort to sue the Saudi Arabian government.

Several U.S. investigations found no reliable evidence that the Saudi government or senior officials knowingly supported the terrorists. The kingdom vociferously denies it.
