Transcript for Donald Trump Reaches Magic Number for GOP Nomination
It certainly was. The race for the white house and Donald Trump sealed the deal formally securing all the delegates he needs for the gop nomination and taunting Hillary Clinton by talking about a debate with Bernie sanders. ABC's Tom llamas is on the trail in Los Angeles. Good morning, Tom. Reporter: George, good morning to you. Reaching that milestone has trump thinking about the future and talking about stat Tuesday of himself as senator sanders says he wants trump one-on-one. Donald Trump turning his campaign swing into a victory tour after locking in that magic number of delegates, clinching the gop nomination. We hit the 1,237, right. 1,237. You know, you had our president saying, he will not be the nominee of his party. Oh, really? Reporter: Trump so confident he's already mapping out his legacy in Washington. Build a wall, it's going to be a big wall. It's going to be a beautiful wall. Someday when I'm gonzo maybe they'll name it after trump. I'd really much rather have a statue in Washington, D.C. Reporter: Naming the price for his next matchup, 10 to $15 million for charity to debate senator Bernie sanders. I think it would get very high ratings. It should be in a big arena somewhere. The problem with debating Bernie, he's going to lose. Reporter: Sanders who requested the debate sounding more like don king than a Vermont senator. And I think we're going to have to rent out the largest stadium you have here in California. Reporter: Telling jimmy Kimmel he's going to come out on top. I will run against him as the democratic nominee for president of the United States and if I do, we're going to beat him and beat him bad. You could tell him that. I'll tell him. Reporter: One person not into the epic clash, democratic front-runner Hillary Clinton. Well, I understood they said that was a joke and I'm going to look forward to debating Donald Trump. Reporter: Trump looking forward to the general election. I want to focus on 15 or so states and I want my energy to be put in the states where it can go either way. Reporter: But Clinton telling voters the fight for the white house is just beginning. Send a message that when you think about the future, you don't see Donald Trump's face up there. Reporter: Today trump heads to Fresno and San Diego where police have added extra officers in case protests grow violent like we've seen throughout the week. George. ING O. Tom, thanks very much.
