He also says that they're going to contract out an independent cost estimate to kind of line up the numbers and get a good independent estimate as well. You know, Kattler, during the hearing, said he was really committed to working with GAO and other oversight entities. He's also asked DCSA's inspector general to audit the INVIS program.
