ms. casper. mr. lewis was department of labor. dhs is january, earlier this year, that are part of what we're reviewing here today. the other two -- well in the epa report, ms. casper you testified -- we calculated about half of the sample purchases, over half there was something wrong, misuse, abuse or noncompliance. and mr. lewis in your testimony, you just testified -- you found about 35% of the purchases with the credit card were abusive or noncompliant. >> that was just with the prepaid debit cards. >> okay. would you estimate on credit cards? that was debit cards. >> well, the issues with the travel cards themselves were actually cases where they should have been using the cards and were not so we lost government air fare. we lost $400,000. >> so you lost money there. so what i'm trying to do is we have 50% abuse. even with a new law, epa use of credit cards, debit cards or credit cards, at least 35% in your review. you have $439 million, almost half a billion in dhs. you did not speak to what you found as like a percentage

ms. casper? >> i also know there are rebates. they get rebates depending on how fast they approve the purchase to be paid. but i don't know exactly what the amount of the rebates was. >> again, this is a small sampling of federal agencies. we appreciate your cooperation. we're looking to see how a law we passed in 2012 worked. there are a number of i.g. reports dating back to january of this year and subsequent reports that we have reviewed for this hearing. pleased that each of you would take time to come in today. our job is to be good stewards of taxpayer dollars and yours are too, particularly the inspector generals, well, all of us, as federal employees. any closing comments? i thank mr. conley and the staff for working during this particular timeframe to make certain we did this. i think we have done a record number of hearings. appreciate your cooperations. many of them like this, meat and potatoes, but important to the people we represent. there being no further business before the subcommittee on government operations, t
