Tweet that some find offensive. A cartoon of Hillary Clinton in black face. That has since been deleted. Pastor burns is a constant presence as a warmup speaker for trump. His latest apology came hours after he challenged by Kristen Welker. But whether his strategy was in fact turning off more black voters than it was attracting. Joining me now is Kristen Welker covering the Clinton Campaign aerokaty tur in Washington State, kristen, first to you. I wanted to play label the of you questioning mark burns refusing to back down, and this was at 5 00, 5 00 eastern last night. Why did you tweet this out . Do you stand by it . Well, i think im pretty clear whats important senior the fact that black face is offensive to black people, but whats more offensive is not so much that theres just black face, but that millions of African Americans are on welfare. Thousands of African Americans are on food stamps. When you tweetd Something Like this out, its impossible for people to hear what you say because this type of image becomes the topic of conversation. Didnt you just because it is drawn to the fact that do the opposite what have donald trump says hes trying to do. But the picture is designed to draw attention to the very fact that Hillary Clinton do pander out to black people. Do you think that a tweet like this helps donald trump to win over more African American voters or do you think it drives them in the other direction because they might be offended . As one of his top surrogates said, this is an inappropriate tweet. Its an inappropriate way of trying to win over African American voters. If you want to talk to me about how i represent donald trump, then we should talk about what bill clinton, who is the husband no, were not talking about bill clinton. Were not talking about bill clinton take a picture we need to talk as though when you talk to the African American community, like that resinates to all of us. Hes not talking to them at all, thats my point. Thats not true. Hes talking to americans. And we as African Americans are americans. Kristen welker, who did not back down, i mean, that was incredible bause we took only a few hours for the tweet to disappear and for him to apologize. Well, i think its what you said in that ultimately did he did back down. He said this was his decision to take the tweet down to ultimately apologize for it. But theres no doubt, as weve been talking about for several days now, the Trump Campaign has retold itself and so, they dont want these types of distractions. Now important to also point out, andrea, he stands by the broader argument that hes making, which is the democrats have been taking African American voters for granted. I have asked for a response from the Clinton Campaign, they wont respond to the tweet or to that criticism directly, but we have married his sustained criticism by secretary clinton essentially saying that Donald Trumps outreach to African American voters hasnt been real because he hasnt yet actually gone to an African American community to talk to them, to make their pitch to them. He is going to do that this weekend in detroit, of course, but she really ramped it up last week when she delivered that speech trying to link donald trump to the altright, to conservative right, some would say white nationalists, and the Trump Campaign has been on defense on this point ever since, andrea. And katy tur, youre in Washington State, and we could ask why hes in Washington State. What do you expect top win in washington . But also, describe for us the role that pastor burns plays out on the stump. Becauses me a frequent warmup speaker at these rallies. Well, first off hes doing a fundraiser here and the Campaign Says that while he is in a state, he might as well do a rally. Donald trump enjoys these rallies and they get national attention. So they feel like if hes here he might as well go out and rally the crowd, even in a state that he is not expected to win. As for pastor mark burns, youre absolutely right. This is somebody who appears very frequently at trump rallies. Hes often the opening act for donald trump. Hes somebody who has been trying to reach out to the African American community directly, hes often said we are all americans, all lives matter, hes been a very vocal proponent of donald trump. So as one of his most high profile African American surrogates, a tweet like this only helps to further the cause that republicans excuse me, democrats are trying to further that donald trump is out of touch with black voters. Pastor mark burns was supposed to help with that, but a tweet that shows no, i didnt black face and the universal outrage that it caused certainly isnt helping their campaign for that particular vote at the moment. But theyre not backing away from pastor mark burns. He has apologized. Which is unusual for this campaign because apologies come very infrequently, but it does prove that even though donald trump has no or defies the laws of political gravity, doesnt mean that everybody around him can do it as well. Katy tur in Washington State and Kristen Welker in brooklyn, thank you very much. And kristina shocky is deputy communication director for the Clinton Campaign. Thanks for being with us. I want to ask you first of all about houma abedin and we knew it was long and coming and unexpected in that both of the wooeiners in the hamptons when this broke over the weekend on sunday night. You know, andrea, i think thats really important with that that we know that huma is just a lovely woman and a wonderful mother. And she has asked for privacy during this very sad and painful time for her family. And we in our campaign are going to respect that and not talk about what shes going through, just out of respect for her, her son, her family. And, you know, i think what we saw yesterday with donald trump is that theres just no low that this man will not go to. It was really hurtful that he used this to attack the campaign and we really think that thats wrong at this time. What about the timing, of course, coming as youre getting into intensive debate preparation, youre less than four weeks away now from the debate, the first of the debates, huma is the most important advisor, described in the vogue magazine which just hit stands yesterday as one of the brilliant strategists in team clinton. You know, i just have to say huma is an absolute pro. She has been such an important member of this team from the very beginning and has worked with hillary for years. And is not only an important advisor, but a close friend. And so, again, were just not going to invade her privacy to talk about this. Shes going through a hard time. And we all support her at the campaign. In terms of the debate preparation, the New York Times has a lead story today about the psych lonl call warfare you might say is going on because your team is consulting psychology experts, trying to figure out a way to get under his skin, to needle him, to figure out his personality profile. Tell me whats going on there. You know, were not going to get into our own debate prep, but i have to tell you that hillarys taking this very seriously. She understands those debates are incredit by important. Thats when you get to talk to millions of voters, your experience, your judgment. What youve done in your life to make a difference for American Families and just as importantly, what are your plans to keep us safe and grow our economy . Shes taking this very seriously, thats how hillary prepares for everything, and shes really looking forward to the opportunity. Trump has boosted and bragged for a long time that he won every debate, hes an incredible debater, and shes taking this seriously and preparing as she does for everything. And really looking forward to the opportunity to talk to people about her real plans, to make college more affordable. To grow jobs and incomes in this country to lower the cost of prescription drugs to make child care more affordable. Shes the candidate in this race will with real plans that will make a difference and shes looking forward to talking to American Voters about that. How do you prepare for donald trump since youre not sure which donald trump will actually show up . Is he going to be the donald trump who insulted marco rubio, insulted jeb bush . The name caller, who insulted Carly Fiorina or megyn kelly or more low key and the business than, you know, the guy who can create jobs . Who knows with donald trump, but one thing we know, theres really no low that he wouldnt go to. He loves to insult people. And we see his judgment and character every day on his campaign trail. And she is just preparing as hillary, as Hillary Clinton does. Shes going to share with people her ideas to make a difference in a their lives and talk about what shes done throughout her life as a lifelong childrens advocate. Who knows with donald trump, but shes taking it really seriously. This is an important moment for her to talk to American Voters and i think we see with donald trump his erratic behavior, his dangerous ideas. Well probably see that on the debate stage, but you know, Hillary Clintons taking this seriously and really looks forward to the opportunity to talk to American Voters. And who could play donald trump . You know, were not getting into our internal preparations, but i just have to say, you know, she is looking forward to the opportunity and she takes this very seriously. And as i said, he has said hes an incredible debater, so shes going to come ready to talk to the american people. And you know, we seen time and again with donald trump, he doesnt really have any real plans. When it comes to the economy, to making college more affordable, and, you know, i think American Voters are going to see that theres a one candidate in this race who has the judgment, who has the experience, who has the knowledge of world affairs, and has real plans to make a dirns in their lives as she look forward to the opportunities tooed that in debates. Were seeing a narrowing in the polls. Theres a lot to talk about in that first debate. Thank you very much, kristina shocky, great to see you. And it is election day. Its a primary day.

Voters heading to the polls today in high straks primaries in two states. In arizona, its veteran senator john mccain, of course, against conservative challenger kelli ward. Who in recent weeks questioned mccains fitness to serve, calling him out on his age. He was 80 years old yesterday. Happy birthday, senator mccain. In florida, former Democratic NationalCommittee ChairwomanDebbie Wasserman schultz fighting to keep her seat against tim kanova. You know why that happened. And victory seems all but sure for incumbent republican senator marco rubio against his channeler, businessman carlos beroof. Our team has it covered for you. Kelly odonnell starting off the Senate Primary in arizona. Following the congresswomans primary and kasey hunt from kissimmee, florida. Republican pollsters are cautioning never be sure of anything out there in arizona politics. And youve covered it so long, you know it better than anyone. Reporter and hell be the first one to tell you that, and we certainly saw them in 2010 when the rise of the tea party and there was agitation towards mccain then. And so in this election, he tells me that he believes youve got to work hard every day. And he talked about that with volunteers here, credited, hes had about 200 young volunteers whove been helping to try to get the vote out. He is confident of the outcome and was already looking toward november and a democratic challenger congresswoman ann kirkpatrick. Democrats see this seat as a potential pickup. They see the changing demographics of the state, and Hillary Clinton at the top of the ticket perhaps helping ann kirkpatrick, and he is trying to fight hard and push, at the same time, he is reluctant to talk about donald trump, recognizes that as a former nominee himself, doesnt want to in any way push aside those voters who got donald trump to the nomination. And needs those conservatives to be with him in the fall. So, mccain is trying to make that balance of fighting a challenger off and then looking toward what could be a much, much tighter race come november to hold on to his seat. Hes seeking a sixth term in the senate, andrea. You caught up with john mccain as you referenced and asked him about donald trump, hes obviously on a very in an awkward position, lets put it that way about donald trump. Lets play it. When you have to position yourself as a republican in a tough environment running with donald trump, at the top of the ticket, how can you separate yourself where you need to . Its not separating myself or anything like that. And i have 100 name id. Ive been here for many years. I dont think their judgment is affected by anything but what they view of me. How they view me. So john mccain being very cautious about the trump factor in that race. And alex psychswald in florida. This could have been a real enlightener with Debbie Wasserman schultz, it a monetary effect, but hanlt moved the polls that much, or was it hard to pl in that strict . Reporter well andrea, she has run six times without facing a primary challenge. This is the first real bid. And it is a tough one. He raised close to 4 million largely from Bernie Sanders supporters, thats bought a huge ground operation that he says can overcome what the polls are saying. Hes down about ten points. He says hes gavelizing voters who dont typically turn out in the low turnout august elections, thats tim kanova. And Debbie Wasserman schultz pulls out all the stops, Hillary Clinton, president obama, major unions have come down and campaigned for her. Shes still looking, you know, very strong. Shes been in this district for, you know, over 20 years, first working in politics, then in the state legislature, then in the congress. Deep ties here. Kanova is arguing shes lost touch with the district, didnt spend enough time here as chairm chairwoman of the party. He lost
