An attorney for a Chicago man accused of terrorism has told a judge she can restore faith in the judicial system by ordering the government to disclose how it may have used enhanced surveillance in the case.

The impassioned arguments came Friday at a rare open-court hearing over whether prosecutors must say if their evidence derived from the spying programs revealed by former government contractor Edward Snowden.

Adel Daoud has pleaded not guilty to trying to ignite what he thought was a bomb outside a Chicago bar.

Defense attorney Thomas Durkin says U.S. District Judge Sharon Johnson Coleman could help restore "lost faith" across the country by ruling for Daoud.

Prosecutors say they are not obliged to reveal that information.
