Clinton needs the excited supporters that have rallied around Sanders and hopes treating the senator's campaign respectfully will make them more likely to back her against Trump. Clinton has already started to make overtures to Sanders' supporters -- pledging to support them even if they don't support her -- and campaign aides have said those will continue in the coming weeks.
"I'm not calling myself that (the presumptive nominee)," Clinton said. "I know there are some contests ahead and I respect Sen. Sanders and whatever choices he's making. And I have a lot of empathy about this, Anderson. You know, I ran to the very end in 2008."
