Trump says the party has to "unite" and endorses Speaker of the House Paul Ryan at a campaign event in Green Bay, Wis. He also endorsed Sen. John McCain (R-AZ), who is in a close primary, and Sen. Kelly Ayotte (R-NH).
"I support and endorse our Speaker of the House Paul Ryan," Trump announced.
"This campaign is not about me or any one candidate," Trump said. "We will have disagreements. But we will disagree as friends and never stop working together toward victory."
