Arlington National Cemetery's management team is laying out new plans to ensure mistakes in labeling plots are not made again.

Earlier this month, an internal investigation led by Army Inspector General Lt. Gen. Steven Whitcomb revealed more than 200 graves at the historic cemetery were mismarked.

Wednesday, members of the House Armed Services Committee questioned Whitcomb and Army Secretary John McHugh on the ordeal.

Army officials said the mistakes were made because of an unorganized and outdated paper cataloging system -- a system still in place despite the Army spending millions of dollars to develop a digital system.

"I'm angry, period," said committee chairman, Rep. Ike Skeleton.  "How in the world could this tragedy be allowed to happen?"

In light of the scandal, Skelton has called for a "100 percent survey" of the cemetery and its operations.
