National Public Radio reporter Daniel Zwerdling spent six months investigating a story that is billed as an exposé of the mistreatment by the Army of soldiers with psychological problems. It will air nationally as a half-hour report this afternoon on "All Things Considered." This morning, though, KPCC will broadcast a condensed version at 2 a.m., 4 a.m., 6 a.m., and 8 p.m. on "Morning Edition." Zwerdling also is scheduled to appear on "AirTalk" with Larry Mantle at 10:20 a.m. to talk up the story and take calls from veterans.
