Nine members of Congress are expected to tour the blood-stained and bullet-pocked halls at Marjory Stoneman Douglas High School on Friday, shortly before ballistics technicians reenact the massacre that left 14 students and three staff members dead.
Few have been inside the three-story building since the Valentine's Day 2018 shooting. The structure looms over the campus, locked behind a chain-link fence for use as evidence in last year's penalty trial for the shooter.
