Donald Trump is optimistic he and House Speaker Paul Ryan will be able to unite the Republican Party despite differing positions on immigration policy, a key issue in the 2016 election.

“I mean, you know, you always have differences. No matter what you have, you’re going to have differences. If you agree on 70 percent, that’s always a lot,” Trump told Fox News host Greta Van Susteren on Wednesday when asked about their differences on the policy.
