bill hemmer and for chris wallace. another major >> i'm bill hemmer in for chris wallace. another key staffer leaving the white house. we'll have more coming up. and, terror hitting an american ally yet again. at least 13 dead including one american in barcelona. >> terrorists around the world should know that the united states and our allies are resolved to find you and bring you to justice. >> we'll discuss how the u.s. is fighting the war on terror with senator ben kardon, the top democrat on the foreign relations committee. plus, as steve bannon joins the list of ousted white house staffers, we'll ask our sunday panel how the shake-up will affect the president's agenda and those that put him in the white house. all right now on "fox news sunday." hello from fox news in washington. the president parting ways with his top strategist after a week that saw the president get harsh criticism from both sides after the violence in charlottesville. where does the white house go from here? with me now, former trump campaign manager, david bossie. first appearance here on "fox news sunday." what took you so long? >> invitation lost in the mail. >> welcome. how big of a loss is this for the president? >> the president is his own aagained -- agenda-setter. don't get me wrong, steve bannon was an integral part of the white house, but this president understands how he got elected. he formulated the agenda and the issues that we really ran on. steve called me in august of last year when he took over the campaign and i came and joined the campaign in late august. so, again, i was somebody that came in late. but we helped the president. it was the president's ideas. it's always been the president's agenda, 100%. for years and years he's been talking about these issues. >> just the other day, the president said this about steve bannon. >> i like mr. bannon. he's a friend of mine, but mr. bannon came on very late. you know that i went through 17 senators, governors, and i won all the primaries. mr. bannon came on very much later than that. i like hill. he's a good man. >> that was tuesday. what changed? >> i don't think anything's changed. i think every staff member serves at the pleasure of the president. there are different chapters in every presidency and staff changes do occur. i do believe that steve bannon will be a very loyal soldier to the president, as it relates to his agenda from the outside. >> you do believe that? >> i've talked to steve many times. he will be a very important voice for the president as it relates to leaning into congress specifically and trying to get the failure of leadership in the house and the senate to stand up and really take ahold of the president's agenda, which if we're looking at seven months on into this administration, one of the biggest challenges the president's had -- they want it all to be leaning on the president when, in fact, it's a failure of leadership in the house and senate. >> who wanted bannon out ? >> look, there are a host and there's has been the different factions within the white house staff and there always is in every presidency. there's no difference here. it's not -- the one thing that i've learned in the last couple of days is in his opinion for the future, this is not personal to him. this is about the president's agenda and the president succeeding on that winning agenda that got him elected last november. >> there are reports that secretary kelly, the new chief of staff, wanted people that only fit into the category that wanted to support president trump. did steve bannon fit in that category? >> 100%. i don't believe for a minute that steve bannon has gone against the president's agenda in any way, shape or form. >> so anyone that would suggest he was working for humself as opposed to the president would be wrong? >> general kelly, obviously the new chief of staff coming in, has broad authority to make changes as he sees fit. he will continue to do that. he wants to have and run a shop that he creates. this is something that -- the reason that steve offered his resignation was to give that general the opportunity to have a clean slate. i think much like reince priebus and sean spicer before him. >> there's an interview late friday night that steve boon did with the weekly standard. "the trump presidency we fought for and won is over. we still have a movement and will make something of this presidency, but that presidency is over." what does he mean? >> he means that congress has failed. what i was mentioning before. mitch mccongress -- mitch mcconnell and paul ryan have to step up and get a repeal of obamacare done. a host of accomplishments that the president ran on and won on. and as a matter of fact, the reason that paul ryan and mitch mcconnell are the leaders are because of the issues that president trump won on. >> with regard to that, bannon said the following -- >> i agree that the house and senate leadership has not bought into the president's agenda fully. and i think the record of the last seven months bears that out. we need to have house and senate leaders come to the white house and work with the president on his agenda. tax reform, our economy is ready to roll. the president has added one million new jobs, no one else. the president with an agenda and belief that every american can have an opportunity in their future and their children's future. that we have the lowest unemployment rate, 4.3%, in over 16 years. the dow is at an all-time high. if we can get meaningful tax reform and tax relief for the american people, this economy is going to be growing at 2%, 3%, 4%. last quarter was at 2.6%. that's the president bringing jobs home, getting corporations to want to hire again, stability. getting rid of the ridiculous, overburdensome regulatory issues that the obama administration burdened business with. >> and republicans in congress may suggest that the white house has not given the leadership what's necessary to push the issues over the finish line. what bannon argued is that the effort on obamacare is half hearted. what is the responsibility of the white house to lead on these issues. >> no one is saying that the president is not leading. there's a lack of leadership on one side of pennsylvania avenue. and so, look, we want everybody to work together. i do. i want the white house and the senate to work together to get the issues on the table and legislative accomplishments through the house and senate that the president can be proud of and sign. >> he also referred to west wing democrats. as you sit here today, there are supporters all across the country. maybe in pennsylvania, ohio, michigan, is wiwisconsin. and they sit in long lines and turn blue counties to red in support of donald trump. how much assurance can you give them today that what they worked for will not be thrown away? >> oh, well, that's easy. the president of the united states is 100% committed to the agenda that he ran on and won on. the agenda of better education, better jobs, better job opportunities and repeal and replace obamacare. to give the american people that hope, growth and opportunity that he promised during the campaign that we have to get done over the next year. >> candidate trump said he was going to come to washington, d.c. and he was going to drain the swamp. did the swamp win this week, david? >> no, no, no. the president is fully committed to draining the swamp. he is in the throes of that fight right now. the swamp, as you drain the water, those creatures come out and that's what this is really about. the president is fighting every day that broken status quo on both sides of the aisle. the broken status quo that has a $20 trillion debt that we will increase the debt ceiling again next month. this is where we need to have meaningful reforms that the president ran on and won on and i'm fully committed to helping him get there. >> thank you for being here today. david bossie, thank you for your time and more to come. in a moment, we'll bring in our sunday group and how steve bannon's departure will reflect his relationship with his base. that's next. 26 vitamins and min. 26 vitamins and min. for the strength and energy to get back to doing... ...what you love. ensure. always be you. that airline credit card yout?

well yeah... but also to catch-up. what's in your wallet? it's about moving forward, not back.t. it's looking up, not down. it's being in motion. in body, in spirit, in the now. boost® high protein it's intelligent nutrition with 15 grams of protein and 26 vitamins and minerals. for when you need a little extra. boost® the number one high protein complete nutritional drink. be up for it >> if you think they're going to give you your country back without a fight, you are sadly mistaken. every day, every day, it will be a fight. >> he's not a racist. i can tell you that. he's a good person. he actually gets very unfair press in that regard. we'll see what happens with mr. bannon. he's a good person and i think the press treats him, frankly, very unfairly. >> president trump on tuesday defending steve bannon, but stopping short of full confidence. juan wi williams and our panel, including bob woodward. president trump said, "i want to thank steve bannon for his service. he came to the campaign during my run against hillary clinton." >> he was a chief strategist and it failed because there is no strategy. you have to be a word person and you have to be somebody that comes out and said, okay, we're going from here to here. it's going take time and this is the plan. and that's not the way that bannon thought. somebody who would make some very loud declarations, serve his purpose. it's very interesting and important. general kelly, as a former four star, is a strategic thinker. you have to be that in the military and you have to have a plan. whether it will work, we'll see, but that's the idea. >> charlie, there's been a lot of reaction. steve king, republican from iowa, conservative side said, "would is going to defend the conservative republican agenda. we're seeing democrats and leftists team up with the nev - never-trumpers." is he right? >> i think he is right. in terms of steve bannon leaving, and i think that bob is exactly right in a lot of ways, bannon is a disrupter. he's not an insider. he's an outsider. he is good at charging the gates from the outside. and i think he will return to doing just that. that's why he was valuable to donald trump in the election. he certainly helped to get donald trump elected. it's not to say that he is somehow trump's brain or anything like that. donald trump and steve bannon arrived at the -- in agreement on so many issues independent of one another. and they both believed them. and i think in that respect, the trump agenda is in good hands. the question is, will republicans on capitol hill defe defend. >> to his base, did they lose this week? >> no, i don't think they did. because trump is still in the white house. trump still believes everything that he did when he ran in the campaign. we have seen him holdfast on things like the environment, illegal immigration, international trade. he's not wavered on any of those things. so, no, i don't think they lost and i think if anything they may have gained a very loud, powerful voice on the outside, who is now unrestrained from white house considerations. >> you wonder if he was ever restrained and steve bannon would argue that no one will restrain him. i thought it was interesting -- newt gingrich with me on friday morning, in a bigger picture, bigger sense for the white house when he said this mr. president trump. >> he's in a position right now where he's more isolated than he realizes. on the hill, he has for more people willing to sit to one side and not help him right now. but he needs to think about what has not worked. and you don't get down to 35% approval and have people in your own party shooting at you and conclude that everything is going fine. >> newt gingrich came on our program to deliver a message, juan. was that message received? >> i don't know. i think that newt is pretty close to the president and i think the president may be watching. this is an important message because there are people who are enablers, if you will, billfor the president that tell him everything is going okay. you are still president trump, you have the energy, the agenda, but if you look at trade, immigration -- bannon said, we should have higher taxes on the rich. that's not in keeping with so much of the agenda that's in the white house and it certainly hasn't been satisfied in terms of legislative accomplishment on the part of this white house. that's why newt said, you are isolated on the hill. you are fighting mitch mcconnell. you are having fights with jeff flake. you have bob corker, who had been a loyal trump supporter saying, this president doesn't look stable or has competence necessary going into the fall, going into fights over the size of the debt limit and the budget. these are troubling signs inside the republican party for president trump at this juncture. >> there are very interesting pieces out today about that i have topic. how do you think this goes from here? >> well, i think speaker gingrich hit the nail on the
