The train reached 106 mild an hour before bostian hit the brakes. He said i remember holding on to the controls tightly and feeling like, okay, well this is it. Im going over. Toxicology reports found no evidence of drugs or alcohol in bostians blood and not using his cell phone at the time of the crash. Lawyer tom kline represents several of hundreds injured.

Tonight is a victory for every american who understands that after we survive eight long years of the obama presidency, that no one personality can right the wrongs done by washington. To the revolutionary understanding that all men and all women are created equal. That our rights do not come from the Democratic Party or the Republican Party or even from the tea party. Our rights come from our creator. And the federal governments role, the federal governments responsibility is to defend those fundamental rights, to defend us. And while americans will continue to suffer, under a president who has set an agenda that is causing millions to hurt across this country, i want to remind you of the promise of scripture. Weeping may endure for a night, but joy cometh in the morning. And we finished second, i want to till you something. Im just honored. Really honored. I want to congratulate ted.

For months they told us because we offered too much optimism in the time of anger we had no chance. For months they told us because we dont have the right endorsements or the right political connections we had no chance. They told me that that we have no chance because my hair wasnt gray enough and my boots were too high. They told me i need to wait my turn. That i needed to wait in line.

And i am excited about really getting into the debate with senator sanders about the best way forward to fight for us and america.

But i believe we have a very clear idea that the Democratic Party and this Campaign Stands for what is best in america. And we have to be united. [ cheers and applause ] when it is all said and done. We have to be united against a republican vision and candidates who would drive us apart and divide us. That is not who we are, my friends. I followed their campaign very closely. I understand what theyre appealing to. And i intend to stand against it. I will not i will not let their divisiveness, their efforts to rip away the progress that we have made, be successful. Because we cant afford that. So as i stand here tonight, breathing a big sigh of relief, thank you, iowa. Iowa, thank you [ cheers and applause ] nine months ago, we came to this beautiful state. We had no Political Organization. We had no money. We had no name recognition. And we were taking on the most powerful Political Organization in the United States of america.
