The Office of Inspector General says that the State Department has lost or improperly filed about $6 billion in contracts in six years.

The mismanagement appears to have begun before former Secretary of State Hillary Clinton’s tenure, but continued through her time as secretary.

Of contracts related to the war in Iraq, 33 of 115 files are missing. Those 33 files alone account for about $2.1 billion in missing funds.

Another 48 of 82 contracts were improperly filed, coming up to about $2.1 billion.

"The failure to maintain contract files adequately creates significant financial risk and demonstrates a lack of internal control over the Department's contract actions," the memo from the OIG said.

The OIG suggests that the State Department create a better organized system. The department agrees.

The Clinton family has not commented on the OIG’s findings.
