WASHINGTON (CNN) -- The United States has not accurately tracked about $6 billion it gave to help the Pakistani government fight terrorism since 2001, according to a report released Tuesday.

"As a result, we conclude that Defense cannot accurately determine how much of the $5.56 billion in costs reimbursed to Pakistan since 2001 were actually incurred," the report said.

The report drew ire from Congress, as some members said Pakistan is bilking the United States to "boost its conventional warfare capability," committee Chairman Howard L. Berman said.
