The alleged Army whistleblower Bradley Manning appeared in court Wednesday for the first day of a three-day pretrial hearing. Manning’s attorneys are seeking the dismissal of 10 of the 22 counts against him related to his alleged leak of a massive trove of government material to the online whistleblower site WikiLeaks. Manning’s defense team says the counts are either unlawfully vague or fall short of amounting to a prosecutable offense. Manning’s military trial is scheduled for September.
