"Does it have to be unified? I'm very different than everybody else, perhaps, that's ever run for office. I actually don't think so," Trump told George Stephanopoulos in an interview that will air Sunday on ABC News' "This Week."
A growing list of Republicans have come out and said they will not vote for their party's presumptive presidential nominee in November, including former Florida Gov. Jeb Bush, South Carolina Sen. Lindsey Graham, and the Republican Party's 2012 presidential nominee, Mitt Romney. But none of that is rattling Trump.
"I think it would be better if it were unified, I think it would be -- there would be something good about it. But I don't think it actually has to be unified in the traditional sense," Trump said.
Trump added that he thinks he'll appeal to voters across the aisle, and gain the support of Democrats to win the general election.
"I'm going to go out and I'm going to get millions of people from the Democrats," Trump said. "I'm going to get Bernie [Sanders] people to vote, because they like me on trade."
