D.C. Superior Court Judge Florence Pan, a nominee for the city’s federal district court, fielded questions from the U.S. Senate Judiciary Committee on Wednesday about her judicial philosophy, her experience as a prosecutor and her decision to grant pretrial release to a suspect in a police shooting.

Law enforcement officials were critical of Pan’s decision to release a defendant pending trial who was charged with firing at police officers. Judiciary Committee chairman Chuck Grassley, R-Iowa, asked Pan to explain the ruling.
