WASHINGTON — The Senate passed legislation Saturday that would require the Army to give a full accounting of every grave at Arlington National Cemetery and fix any errors found at one of the nation’s most sacred military burial grounds.

The bill would also require the secretary of the Army to report to Congress on its progress in reviewing and overhauling the management of the contracts at the cemetery.

The bill comes after the recent discovery of hundreds of lapses at the cemetery, including unmarked and improperly marked gravesites, and the Army’s announcement of its first criminal inquiry into the scandal.

The failures occurred despite federal spending of $5 million to $8 million on contracts to modernize the cemetery’s antiquated record-keeping.

On Friday, an Army official confirmed that a criminal probe is looking into how eight containers of remains ended up in a plot that was supposed to be holding a single set.  

“I am outraged that the problems continue to surface at Arlington Cemetery,” Sen. Claire McCaskill, D-Mo., said in a written statement.

In June, the cemetery’s superintendent and his deputy stepped down after the report by the Army inspector general found more than 200 unmarked or mislabeled graves in three of the cemetery’s sections.

The bill’s five co-sponsors include McCaskill and Sen. Susan Collins, R-Maine. A spokeswoman for McCaskill said a companion bill must still be sponsored in the House.
