porcari, mr. lahood said others could experience up to 90 minutes during peak hours because we fear are controllers on. mr. meadows tells me last week in transportation and infrastructure committee dfa at the straighter it did under questioning the 90 minute delays and cities are not based on data or study. is that true? same question to mr. miller. do you have databases going to happen? i flew this week and it didn't happen to me. >> we know impacts your chicago would be a good example. by having less controllers on duty, chicago has two hours. but not in the north tower -- >> is there any study that indicates this is going to be the case? if so, with the faa administrator mifflin in the transportation infrastructure committee last week when he said there's no data that this is the case. >> it is difficult to measure precisely until the cuts are in effect. we know have a significant impact in the primary impact will be on our busiest -- >> once again it was a gas. the secretary of education and t

porcari has just said? >> on the basis of our available data, it appears to be accurate. if i could return to one of your earlier questions, and i do want to make sure that the record of this committee hearing is accurate. i certainly don't want to be in a position to have misled the committee at all. when i spoke of the conference expenses for fiscal year 2010, i had also hoped to bring to the committee's attention that the department reported to this committee for fiscal year 2011, having spent $3.40 million and 23 conferences for fiscal year 2012, $668,000 for 11 conferences. 2010 appears to be an unusually high number and has come down since then. these are not audited figures but they had been supplied by the department to the committee. >> before rider time runs out, and i thank the chair for his graciously allowing us to answer earlier, but you are accused of scaring the public. will there be furloughs among faa employees, including air traffic controllers, and will that affect flight patterns and delays at the airport? will there be furloughs of employees and cust

porcari, you said that 3/4 of your budget is exempt, basically. >> that's correct, 74% is exempt. >> when you have -- when i look at bwi in baltimore, they've already got about 258,000 flights per year. at some point, something has to give. they are right -- they are already flying from 5:00 in the morning until midnight. what gives? >> that is an excellent question. flight delays is like throwing a rock in a pond. it ripples through the entire system. you may have flights taking off late or cancellations. most passengers are moving to a hub, they may miss their connections. those connections are tied together. we cannot fully quantify what all the impacts are. we believe they will be significant and it is important to point out that they are cumulative in the sense you're airport experience also includes the tea s.a. delays to get -- the tsa delays and the flight beyond that. >> exactly where is your responsibility and and there's began? you talked about possible criminal investigations -- you also talked about the money that has been lost -- where is the line there? >> understand -

and the honorable john porcari is deputy secretary at the u.s. department of transportation and d.o.t.'s chief operating officer. the honorable calvin l. scovell -- i'll get it right, scovell is the inspector general of the department of transportation and as many of you have seen a c-span, pursuant to our rules, which you please rise to take the oath. raise your right hands. do you solemnly swear or affirm the testimony about to give would be the truth, the whole truth and nothing but the truth? let the record reflect all witnesses answered in the affirmative. this panel is extremely important to us. your opening statements are on the record and our integrity. to the greatest extent possible, if you limit yourself to the five minutes summarize where appropriate, we'd appreciate it and that will leave more time for the q&a i know you are all looking forward to. with that, mr. miller, if you have laid off. >> thank you, mr. chairman. ranking member cummings, thank you or the opportunity to testify to improve efficiency, reduce fraud and waste. my
