In light of reports that two employees at the National Personnel Records Center in St. Louis, Mo. admitted to dumping, destroying, or misfiling at least 1,800 documents held by U.S. veterans, U.S. Senators Roy Blunt (Mo.) and Claire McCaskill (Mo.) sent a letter today expressing their concerns for the veterans’ surviving family members who have been affected by this potentially harmful breach of their personal information.

According to the St. Louis Post Dispatch, “Court documents in the unemployment case say some employees, seeking to earn a bonus, were intentionally ‘stashing’ records to finish more quickly, and that those documents may never be found among the vast holdings.” The Senators requested information on what steps the National Personnel Records Center is taking to prevent such a serious incident from happening again.

“How many surviving family members have been impacted by the release of the names and Social Security numbers, and have they been advised of the breach? Have their benefits been impacted by this incident in any way?” the Senators wrote. “What policy changes have been recommended or implemented as a result of this breach of personal information?”
