FORT MEADE, Maryland (Reuters) - The U.S. soldier accused of providing classified files to WikiLeaks told his aunt a leaked video of a helicopter attack in Iraq that killed civilians would cause a "big splash," she said in a statement at his court-martial on Tuesday.

Private First Class Bradley Manning's aunt, Debra Van Alstyne, told Army investigators about his comment when they talked to her at her Potomac, Maryland, home in June 2010, after his arrest, according to a statement read into the trial record.
