>> Donald Trump's rise against all odds to the top of 2016 Republican presidential ticket marks the total collapse of the old guard of the Republican Party and the emergence of a new party, one with Trump's name stamped in block letters across the door. I'm Steve Holland at the Republican National Convention in Cleveland.
With his son Don Jr. doing the honors, Trump went over the top in the delegate count. It's now Trump's party and he's calling the shots, and he did all this despite resistance from the Bush family, donor elites, Mitt Romney, the entire establishment Republicans. But grabbing the nomination does not mean the fight against Trump is suddenly over.
He still has a long way to go. And the thankless task of trying to unite the party fell to House Speaker Paul Ryan, who hasn't been all that excited about Trump in the past.>> Have we had our arguments this year? Sure we have. You know what I call those?
Signs of life, signs of a party that's not just going through the motions.>> Donald Trump, he's attacked some of the central tenets of the Republican Party and he's turned the party upside down. And now many conventional Republicans are thinking, my goodness, maybe we need to change our policies, too.
There are also concerns among some Republicans about his temperament, that his rhetoric is too bellicose, that he seems to throw temper tantrums. And they don't think that's the kinda behavior the United States needs in a world leader. Trump plans to come here on Thursday and accept the nomination with a speech detailing his vision.
>> This is going to be a leadership, by the way, that puts the American people first.>> As a sign of just how dramatically he plans to change things, we're reporting exclusively tonight that if he's elected, he would seek to purge federal appointees appointed by President Obama from the federal government.
