Presumptive Republican nominee Donald Trump fell short of winning an endorsement from House Speaker Paul Ryan Thursday but both men said they had taken a "positive step" toward unifying the party behind the billionaire's remarkable White House run. Trump, facing a critical early test of his general election candidacy, met with Ryan to air their differences, and with other Republican leaders. In a joint statement afterward, Trump and Ryan called their meeting a "positive step toward unification" and stressed the party's paramount goal is to defeat Democrat Hillary Clinton in November.
