more money for an accelerating american covid vaccine rollout now climbing past 109 million doses administered. that means more than one in five americans are now at least partially vaccinated. the global vaccine rollout also a big issue today, especially across europe. a few dozen recipients of the astrazeneca vaccine report dangerous blood clots. a growing list of countries now suspending use of the astrazeneca vaccine, including france, italy and germany. world health organization and european experts are taking a new urgent look at the issue. but the executive director of the eu agency that regulates vaccines says every piece of available data says the astrazeneca vaccine is both effective and safe. >> at present there is no indication that vaccination has caused these conditions. they have not come up in the clinical trials and they're not listed as known or expected side events with this vaccine. we are still firmly convinced that the benefits of the astrazeneca vaccine in preventing covid-19, with its associated risk of hospitalization and death outweigh the risk of these side effects. >> back to that story in a moment. first, though, the president's road trip, his stop is about highlighting a giant legislative achievement and trying to sell the idea that government must be trusted to help deal with big problems. the president's first stop today is an interesting choice. we remember this map from the 2020 election, pennsylvania absolutely critical to joe biden. he'll be down here today in the philadelphia area, first montgomery county, and then come over to philadelphia, and then just south, delaware county the city of chester, chester part of delaware county, chester itself a small majority black city. look at this, 34,000 population, 69% of the population where the president will be today is african-american. the median income below the national average, well below it, $32,000, nearly one-third of the citizens of chester live in poverty. so a place where stimulus checks, family tax credits, new economic assistance, helping getting schools opened desperately needed and the president hopes significantly welcomed. kaitlan collins joins us from chester where the president will be shortly. >> reporter: the president is going to be here visiting a small business while he's here. we don't know which one yet. but we'll find out in a few miles per hour when he gets on the ground. they are saying this is a city like this is what proves the point of why they pushed to get that massive coronavirus relief bill through and they're saying that it's not just chester, it's all of pennsylvania pointing to numbers like the ones here about how this bill -- that the president signed into law last week is going to affect the people that live here, not just the money for states and localities but also the money for schools, the child tax credit and the enhancement there, that's what he's on the ground selling and talking about their efforts to help small businesses. they're saying it's places like this, and people who live here and places like chester, pennsylvania that actually need this help, that need those stimulus checks, that need the child tax credit, of course who we were talking about earlier, is talking about lifting children out of poverty and they believe this bill is going to do that. you're right, this is not just a salesmanship for this bill and talking about the implementation of it, it's also aspects of it that they want to make permanent, including the child tax credit and the changes there that are temporary in this coronavirus relief bill but is something that president biden and his top aides want to see made long term. so that's what you're going to see when he actually gets here on the ground selling that message. it's one of many stops the president and several top aides including the first lady are taking this week, john. starting here but expect to continue to see this message in these critical states going forward for the rest of the week. >> kaitlan collins on the ground for us live reporting, chester, pennsylvania, appreciate that very much. let's discuss this further now with dana bash and lauren lopez. following up on the point, a giant legislative achievement but also about watch how this works, that check in your bank account, that aid to help your school reopen. more money to reopen vaccine sites. republicans are arguing big spending by the democrats, whether the next issue is infrastructure or climate change, the republicans are going to say too much government, too much money, joe biden's trying to say you need government help and i'm going to prove it can work. >> all the reasons kaitlan gives why the president's team thinks chester pennsylvania is important in the content. and also -- always the swingiest of swing areas, especially in the upcoming midterm elections. that speaks to one of the reasons why they're doing this, because it's to explain and protect his legacy and his initiatives, the biggest of which so far, of course, is this covid bill but it's also to help protect the democrats who voted for it and help explain to their constituents that it's not just big government from their perspective, this is things that people who have very much been suffering from this, from teachers to small business owners, to, you know, keep going on down the list, need this money, and, you know, particularly in a place where people historically are fiscally conservative and maybe socially more progressive seeing a $1.9 trillion spending bill is eye popping, and will probably take a lot to swallow in terms of support. >> so they need to prove that it works. laura lopez, one of the other challenges of being president is you don't get to pick what comes across your desk. the president wants to explain to people what they're getting today and tomorrow and the next year or two as this money is spent out. at the same time he plans what next to ask the congress, he has -- what the republicans call a crisis, call it a challenge, the major problem at the u.s.-mexico border. record numbers of minor unaccompanied children are held in conditions that are not up to par for them. trying to send the message, please don't come now. >> it is not ever a good idea to come in this irregular fashion. it is a more humane system, but it is not open borders. >> do not come now. give us the time to rebuild the system that was entirely dismantled in the prior administration. >> however, even democrats, especially border state democrats say there's a problem here, that the administration might be saying from the president on down, please don't come now, please give us some time but the administration is also saying we are not the trump administration. if you come we are going to treat you humanely, if you come we're not going to make you stay in camps in in mexico. and that's not the way the message is being received despite what the white house is saying. >> the message has to be clearer in central america. one is from the president saying don't come. the other one is the family friends network that get over here, then they tell their friends and family i was able to come through. this friday i was there and i talked to some of the people that had come across, there were about 20 of them. i asked them which message have they heard? never heard the president. >> how do they fix that? >> you know, there's a lot there for the administration to tackle, john. and there's a lot that goes into what leads migrants to actually make that dangerous journey. statistics actually show there are more mexicans coming to the border now than central americans. even though the administration is saying that they are going to try to be -- establish a more humane system they are still expelling migrants via an authority, a public health authority that was established under the trump administration, one they haven't gotten rid of yet and they are still expelling a large number of migrants. what the administration is trying to do is build up more capacity so they're trying to work with youth organizations as well as foster care organizations in the local areas to try to get more shelters and as you said, get these children out of cbp facilities faster. but this is an issue that a lot of house democrats -- well all democrats, not just house democrats are concerned about because of course there is politics and the republicans are going down there to try to really hammer the administration on it. i'm also told by some hill sources that secretary mayorkas who you just played a clip on, that he is expected to talk to hispanic caucus members this week and there's going to be a lot of questions about that when he does. >> quite a lot of questions about that. this is the challenge of a new administration, day 56, some things you can't control. there's also, dana, this urge among democrats that we have power now. it's been a long time. we have power now, let's use it as quickly as possible. while the president would like to be on the road talking about covid relief, taking his time to think about what's next, you have democrats saying what is next? bring the immigration bill to the floor, infrastructure, and climate change. one of the questions, especially on the infrastructure bill, is, are you going to raise taxes? vice president harris is on the road to talk covid relief but of course questions follow you. listen. >> can you say whether tax increases are under consideration as part of the next phase of this recovery act? >> we haven't figured out what the next phase is going to be, to be honest with you, we're going to make those decisions, this just happened last week. we want to get on the road to make sure people know what it is. >> another right answer. punt a little bit right there but that is part of the challenge, so much pent up energy to act and to do things, especially, you know, you mentioned the midterm elections, november of next year may seem like a long way off. democrats think we could lose power. use it while we have it. how do you handle the tax debate? >> they clearly don't know the answer yet. one of the more immediate questions is what is going to be the next piece of legislation, is there actually something that they can work with republicans on? is infrastructure that, or is it not? once you get into the details things quickly become partisan, despite the fact that all sides, like the idea of doing something like infrastructure, and so, you know, we don't know what they're going to do when i say they it's what the administration is going to push. we are already seeing, you know, bill after bill that the house is pushing because it's much easier to pass things in the house that do live up to their campaign promises from so-called hr-1 voting rights to, you know, gun -- more restrictive gun laws on and on and on and immigration, a couple of bills, sort of smaller bills will go through the house this week. the question is, where is the administration going to put its energy and its focus and i don't think we know the answer to that yet. >> we don't know the answer yet. i'm going to talk to two democratic senators later to continue that part of the conversation. up next for us, focus on covid,
