NEW YORK (Reuters) - Lawyers for Osama bin Laden's son in law peppered U.S. officials with questions on Tuesday about his interrogation earlier this year as they seek to have those statements suppressed as evidence in his upcoming trial.

Suleiman Abu Ghaith, described by U.S. authorities as a spokesman for al Qaeda, faces trial in federal court in New York in January on charges he conspired to kill Americans. He has pleaded not guilty.
