Family members of an Arizona U.S. Border Agent killed in connection with a botched gun-smuggling operation say they won't have closure until someone is held accountable for his death.

Brian Terry's mother, sisters and cousin from the Detroit area are in Tucson for a banquet Monday evening to raise money for a foundation set up in his honor. They'll also go to Naco on the Mexico border Tuesday when the Border Patrol station there is renamed for him.

The Republican-run House wants a federal court to enforce a subpoena against Attorney General Eric Holder, demanding that he produce records on Operation Fast and Furious.

And the Justice Department's inspector general is scheduled to be questioned Thursday before a House committee about his findings on the operation.
