WashPost: Campaign's finance director Mantz held a series of conference calls with major donors Tuesday "to urge them to throw their financial weight behind" Obama.
Source familiar with the calls: "Honestly, reaction has been mixed. There are a lot of hurt feelings out there. And a lot of folks that want to make sure Hillary is respected through the remaining process."
Obama campaign manager Plouffe is expected to huddle with a number of Clinton donors later this week in New York City.
Plus: Clinton also reaches out to delegates in private conversations, conference calls, asking them to vote for Obama at the convention.
