Asked on NBC's "Today" show whether he was confident he could unite the party, Trump responded, "I am confident that I can unite much of it. Some of it I don't want.
"There were statements made about me — those people can go away and maybe come back in eight years after we serve two terms," he added. "Honestly, there are some people I really don't want."
Trump's remarks came after the interview began with clips of former rivals, including Lindsey GrahamLindsey Olin GrahamTrump: I hope voters pay attention to Dem tactics amid Kavanaugh fight Graham calls handling of Kavanaugh allegations 'a drive-by shooting' Graham knocks South Korea over summit with North MORE, Jeb Bush, Marco RubioMarco Antonio RubioRubio unloads on Turkish chef for 'feasting' Venezuela's Maduro: 'I got pissed' For Poland, a time for justice Judiciary Democrat calls for additional witnesses to testify on Kavanaugh MORE, Ted CruzRafael (Ted) Edward CruzGOP candidate scores upset win in Texas state Senate runoff McConnell tamps down any talk of Kavanaugh withdrawal Cornyn takes on O'Rourke over AR-15s MORE and Carly Fiorina, predicting he would not become the Republican nominee.
Trump clinched the title of presumptive GOP nominee with a win over Cruz in the Indiana primary on Tuesday, forcing the Texas senator to suspend his campaign.
Trump's win in Indiana puts him on a clear path toward the nomination, with 1,047 delegates, according to The Associated Press. He needs 1,237 to clinch the nomination; without Cruz in the race, he is all but guaranteed to hit that number.
