And this morning, donald trump is drawing scorn from both sides of the isle aisle after mocking senator mccains war record. This seemingly has to be the last straw from his last gop rivals. Abcss cecilia vega is here. Reporter good morning, guys, another week, another political firestorm courtesy of donald trump, just as quickly as he lobbed an attack the hits came right back at him. Youre fired. Reporter this morning, donald trump has the political world fired up once again. But this time, he may have gone after the wrong person john mccain. Hes not a war hero. Reporter the brash billionaire saying john mccain, a former navy fighter who spent 5 1 2 years as a p. O. W. During the vietnam war, was actually no war hero at all. Hes not a war hero. Hes a war hero because he was captured. Reporter well, fellow republicans did not like that. Nearly every single gop candidate running for the white house firing back. I will denounce anyone anyone who speaks ill of somebody whos been a prisoner of war. Reporter former Florida Governor jeb bush tweeting, enough with the slanderous takes. Former Texas Governor rick perry saying, trumps comments make him unfit to be commanderinchief. Mccains daughter saying shes horrified, disgusted, there are no words.

Martha, the New York Times also saying, im quoting here, probably mark the moment where trumps candidacy went from boom to bust. Whats the sense in washington, can he survive this . Well i think you just have to look again at those comments that cecilia went through right there and remember, john mccains service, he said that hes only a war hero, said donald trump, because he was captured, i think it would be pretty hard for john mccain not to be captured. He was shot down, i think he was on his 28th Bombing Mission over north vietnam, broke both legs as he ejected from his aircraft. Broke an arm. He was tortured as cecilia said held 5 1 2 years. All of those comments saying, its not just about john mccain, its also about veterans, and we still have a lot of Service Members out there fighting on the battlefields, around the world. Criticism from the Republican Party has been much sharper on this than trumps comments on mexican immigrants. I think the Republican Party, there have been statements from the Republican National committee as well they have come together and have said these are completely inappropriate comments. I think some people will try to step in and say, wait, wait, im moderate. Rick perry, whos also a veteran, asking for trump to step aside. Trump is not known for backing down. Do we think well see an apology on this one . Boy, we havent seen one yet, dan. I dont know. He really doubled down after making those comments. Well have to wait and see if theres any apology forthcoming. I just cant predict that. Martha raddatz, we appreciate your analysis on this sunday morning.
