city of raqqa. it could be a prelude to an assault on the city itself. >> woodruff: in greece, officials began moving migrants today from a makeshift refugee camp near the northern border with macedonia. police managed to get about 1,500 people to leave the squalid idomeni site and move to other, better organized facilities. they piled into buses, and bulldozers removed what was left of their tent shelters. separately, the international organization for migration reported fewer migrants are dying as they try to reach europe. that's largely because turkey has curbed the overall flow. >> back in this krish the justice department announced late today that it is seeking the death penalty for the killings at a church in south carolina. dylan roof is accused of gunning down nine black parishioners last june. he faces 33 federal charges, including hate crimes and firearms offenses. >> sreenivasan: comedian bill cosby will stand trial for allegedly drugging and sexually assaulting a woman in 2004. a judge in norristown, pennsylvania issued that ruling today. cosby left the hearing without commenting, but the prosecutor said statements to police-- back in 2005-- established "probable cause". >> a preliminary hearing is a situation where we only have to show that a crime is committed and the defendant is connected to the crime. we did that through the victim's statement and the defendant's admissions to much of the crime. >> sreenivasan: a defense lawyer said cosby's rights have been violated, and he'll appeal the ruling. more than 50 women have claimed he assaulted them over the years, but this is the only criminal case so far. >> woodruff: there's word that kenneth starr is out as president of baylor university in texas. he was the independent counsel who investigated president clinton. several broadcast and online outlets reported today that starr has been fired over his handling of allegations of rape leveled against male athletes at the school. baylor labeled the report "rumors." >> sreenivasan: for the first time, more than 40 major health groups are recommending weight- loss surgery as a routine option for treating diabetes. the new guidelines include patients who are only mildly obese. some 26 million americans have diabetes. >> woodruff: the smoking rate among american adults has fallen-- by the most in more than 20 years. the centers for disease control and prevention says 15% of adults classified themselves as smokers in 2015. that is down from 17% the year before. it's unclear if the rise of e- cigarettes played any role. >> sreenivasan: monsanto today rejected a takeover bid by german chemical giant bayer. it was valued at $62 billion. and wall street had its biggest day since march. the dow jones industrial average gained 213 points to close at 17,706. the nasdaq rose 95 points and the s&p 500 added 28. >> woodruff: still to come on the newshour: a shakeup at the t.s.a.-- will it help cut down long airport lines-- congress at odds over zika funding with mosquito season fast approaching, a tax on sugar drinks to pay for pre-school, and much more. >> sreenivasan: if you've traveled on a plane recently, you've likely seen something different at the airport-- extremely long lines. it's a problem roiling the government, airlines and the public. >> one on the left, one on the right please. >> sreenivasan: at airports across the country, frustration is boiling over as security wait times soar. >> i've missed three flights because of, you know, standing in line. >> look at the chaos that goes on here, and every checkpoint is like this. >> sreenivasan: now, the transportation security administration has sacked kelly hogan, the man in charge of day- to-day security operations. he's had a checkered three-year tenure. in 2015, a homeland security report found t.s.a. employees failed to find banned items in more than 95% of covert tests. and there've been allegations that hogan played a role in punishing whistleblowers. then, there's $90,000 in bonuses he received between 2013 and 2014. that issue riled the chair of the house oversight committee, at a recent hearing with t.s.a. head peter neffenger. >> those bonuses were given to somebody who oversees a part of the operation that was in total failure. >> sreenivasan: dissatisfaction with hoggan came to a head last week, when hundreds of passengers missed flights at chicago's o'hare airport-- after waiting for hours. >> this was always avoidable. we have a situation that is totally not tolerable for the flying public because of people responsible were not doing the job they needed to do in funding, but also staffing positions. >> sreenivasan: the t.s.a.'s neffenger says his agency has struggled with budget cuts at a time when more people are flying. another concern: relatively few people signed up for t.s.a.'s expedited pre-check procedure. congress has voted an additional $34 million to hire nearly 800 more screeners, but neffenger says that's not enough. today, the union for t.s.a. one is overall staffing for screeners is down something like 5800 screeners since the peak in 2011. they have about 42,500, but it's much fewer than they used to. that i.g. report that found they weren't catching much last summer has prompted them to check bags more thoroughly, so they're taking a closer look at you as you go through the lines. they're going to redo that undercover-up investigation this summer to see. they're catching more. neffenger says they are catching more. and we are also seeing more travelers than ever before. the airlines for america expects 231 million travelers this summer between june 1 and august 31. >> sreenivasan: so what's the ripple effect on the traveler? when we saw and heard those people say how many flights that they've missed. cumulatively this has to be a lot of business concern for the airlines, too. >> yeah, the concerns -- it's a headache for the airlines because anybody missing a flight, trying to rebook them, the flights are going almost 90% full. it's dill. american airlines said during a single week in mid-march they had 6800 travelers miss their flights because of the security screening. that's why airlines for americas orged a hashtag and web site called the hate the wait to try to get more public acknowledgment to the problem. >> sreenivasan: we were talking about camera for global entry. i was going through the t.s.a. precheck lines. how many other people are joining me in this and how does that factor in? >> overall, there are 10 million people in expedited screening programs so far. about 2.5 million of them are specifically precheck, which is the t.s.a. program. if you're in global entry through customs and border protection, that gives you the added value when you're coming back from overseas, you get to go through the customs lines faster, scipt long lines from the airlines. they're trying to recruit more people into these programs, but so far they're falling well below 10 million total members, they're falling far below their goal of 25 million in these expedited programs. >> sreenivasan: have these point increased the number of applications? >> they were getting 2,000 to 3,000 applicantaise day at this time last year. now they are up above 10,000 a day. last week, neffenger told us this morning they got 15,000 people in one day. >> sreenivasan: you met with neffenger this morning before the news about hoggan came out. what was the mood there? >> well, yeah, he set up-- we had an editorial board arranged with him before this news broke. he was very forthright saying that he didn't say that hoggan had done something wrong. he just said he wanted a change of strategy. he wants to try to make the lines more efficient, rather than just going faster for people. they don't want to sacrifice security for moving the lines. nevertheless, they think they can move the lines for efficiently and get people through faster. >> sreenivasan: almost every travel agent i speak with says it's going to get worse through the summer. >> yes, the secretary of homeland security, jeh johnson, has warned even as they add the screeners that was mentioned in your report, that lines are still expected to be long. you should plan ahead. but they are going to try to avoid the two- and three-hour waits that you've seen in the last few weeks. >> sreenivasan: all right, bart jansen of "usa today," thanks so much. >> thank you for having >> woodruff: now: to capitol hill and washington's efforts to combat the zika virus. back in february, the white house put together a $1.9 billion proposal aimed at mosquito control, education about zika, plus, boosting research into the virus, and a possible vaccine. last week, the republican controlled senate moved a compromise measure, for less than two-thirds that amount over the next year-- $1.1 billion. but the also g.o.p-controlled house signed off on a bill for $622 million, over six months. joining me now from opposite sides of this funding divide are representative rosa delauro, a democrat from connecticut, and representative bob gibbs, republican from ohio. and we welcome both of you to the program. congressman gibbs, let me begin with you. the administration, as we said, asking for $1.9 billion. the amount you favor is about a third that much. why not give the administration what it's asking for? >> well, what the administration did that's ongoing through at least the next two mosquito seasons, our bill, at $600 million-plus, goes to the end of the fiscal year, september 30, and now we're in the appropriation process, and we'll look at that, what we need to do past september 30 of this year going into the next fiscal year and the next mosquito season next summer. we'll be appropriating more money, i'm sure, but it's going to go through regular order and the regular appropriation process. we're on board to make sure to appropriate the money that's needed to get through to the end of this fiscal year. >> woodruff: congresswoman delauro tsound like a down payment on this problem. does that sound like it will be enough? >> the fact is the zika virus is a public health emergency. it is a crisis. it is going to the mosquitoes that carry the virus will hit the mainland united states within the next few weeks. we are putting american women at risk, pregnant women, who are fearful that their babies will be born with birth defects. and we have a medical community that is telling women that maybe they should not get pregnant. that is not message to the american people. the fact of the matter is, is that the $622 million is a third of what's been asked for. you know, in this body, when we deal with appropriations for defense or going to war, my republican colleagues will say, "let us get the word from the generals, from those who are in the field, the experts. they can tell us how much money they need. and they can tell us how many troops we need." well, we do have experts in this war on the mosquitos. we have the center for disease control. we have the national institutes of health. we have the scientific community, all of whom said we need $1.9 billion. and they have documented every cent of that as to where it is going opinion we need to listen to these generals in the field on this war on the mosquitos. and keep the american public safe and american women safe. >> woodruff: congressman gibbs, it's not just democrats who are saying that this is not enough money. one of your fellow republicans in the senate, marco rubio, of florida, said today that this is not enough money, the $622 million. he went on to say that he fears that the opportunity to get ahead of this crisis is slipping away. what do you say to him? >> well, i think we're going through the appropriation process, and if it's not enough money we'll do the appropriation bills here in the next few weeks, and we'll appropriate more money when we go through request & do our due diligence. but another issue i need on talk about is my bill, 897, deals with how we control mosquitoes and kill the larvae in mosquitos here before they hatch, and that's a bill i had on the floor today, passed with strong bipartisan support. and it gives our states and local communities the resources, the ability not to have additional red tape and bureaucracy and don't waste resources to do their control efforts, to start doing the preventive programs, the onset at the beginning of the mosquito season. and that's really important and a lot of people on the other side of the iefg are not supportive of this and it's really something that needs to be done so our local communities, mosquito-control districts have every tool in the toolbox to start preventive programs to stop the mosquitoes from growing in population and possibly reaching epidemic proportions of the zika virus or even the west nile virus. >> woodruff: congresswoman delauro, my understanding this legislation that the congressman is referring to would loosen the restrictions on the use of pesticides. is that at least a partial step in the right direction? >> let me make two quick point to you. we running out of time. it was anthony fauci at the n.i.h., at the center for infectious diseases, who said that if we wait for the appropriations process, we are not going to be able to do what we need to do to get ahead of this virus. on the bill that my colleague has introduced, let me be clear with all due respect to my colleague, it is a phony. it is a sham. it is nothing but trying to weaken the environmental regulations. it exempts, broad exemption of toxic pesticides from the cleann water act. this bill was introduced two or three years ago, has noct to do with zika. our states and municipalities today have the authority in which to be able to control the mosquito population and to-- and to deal with it. this will only pollute our rivers and contaminate our water. this bill that was passed today has nothing seriously to do with controlling the zika virus. it's rebabd branded. >> woodruff: congressman gibbs. >> the american mosquito control association has said we have had communities that are slow to get the preventative mosquito control programs up and going because of this court case that created this praib few years ago. and the e.p.a. has full control over the-- under current law, to regulate these pesticides, and if these pesticides have restrictions have to be applied by a certified applicator and they have to keep all kinds of records. we saw, we have testimony from mosquito control entities throughout the country that said that they've add the cost to the paperwork, and it also opens them up to litigation, and if they are in violation of the paperwork under the clea clean r act they will be find. >> again, very quickly, we are-- what's happened is the emergency preparedness money has been taken away from localities because the c.d.c. has had to shift money because this congress, this republican congress will not appropriate the $1.9 million, which makes it slow for them to deal with surveillance. the fact is, is that under emergency circumstances, our states and our municipalities have the authority to deal with controlling the mosquito population. this bill will do nothing to address that issue. >> woodruff: congressman gibbs-- >> reaching epidemic proportions they will do emergency measures and not need any permits and start a preventative program like they normally would. >> woodruff: congressman gibbs, i want to ask you what this says to women who live in areas that may be affected by the mosquito carrying the zika virus. what do you say to women who are worried, who are concerned that the mosquitoes are coming with the warmer weather? >> well, it's obvious we have to do everything we can, and i think the money that we voted last week in the house to put-- start the process moving forward, and i'm sure we'll appropriate more money as soon as we learn it's necessary. we don't want to create just a slush fund out there with no accountability. we're doing our due diligence. the president's request goes out-- has no time frame. just goes on. so we've got this set to september 30, and before september 30 we can appropriate more money. it gets the ball rolling, and my bill gets the ball rolling so our locals can start their preventive mosquito control programs. >> what we are saying to women, we're saying to women that you are at risk. without trying to deal with this, with the immediacy that the specific community has told us about, this is immediate. it's now, in a few weeks. that means this summer. women are going to be afraid to go out on their patio. they're going to be afraid to go to a barbecue. they're going to be afraid to take their kids to little league because it can put their ability to have children or if they're carrying children, they would be in jeopardy. this puts american women at risk, and this congress is doing nothing but stalling, this republican congress has said no five times to $1.9 million, which is well documented, it's more documented than the war in iraq was. >> woodruff: we'll have to leave it there, congresswoman delauro, congressman gibbs, we thank you both very much. >> thank you. >> thank you. >> sreenivasan: stay with us. coming up on the newshour: a first for presidential candidate donald trump-- hosting a fundraiser. balancing the interests of ranchers and conservationists in the american west, and a woman's life entwined with science and nature. but first, the city of philadelphia is considering a new but controversial way of funding early education. here's my report-- part of our weekly series on education that airs on tuesday nights called "making the grade." in philadelphia, buying soda has bubbled into a political controversy. to make pre-kindergarten available to all three- and four-year-olds, philadelphia's mayor has proposed a soda tax that requires beverage distributors to pay three cents for every ounce of sugary drink sold in the city. >> philadelphia's chance to lift our children with citywide pre-k is now. >> sreenivasan: the mayor hopes to raise $95 million annually with the new tax. but unlike campaigns in other cities, philadelphia's soda tax is not being promoted as a health issue. >> the ancillary benefit to this will be healthy choices, but it's not the purpose. the purpose of imposing this three cent an ounce sugar- sweetened beverage tax is to allow people to get their kids educated and move them out of poverty into taxpaying
