Obama and Clinton spoke Sunday night and agreed that their staffs should begin negotiations over post-primary activities, according to reliable sources. In addition to seeking Obama's help in raising money to pay off some $20 million-plus in debts, Clinton is known to want Obama to assist black officials who endorsed her and who are now taking constituent heat, including, in some cases, primary challenges from pro-Obama politicians.
"This has never happened before," one donor said, referring to the personalized request by email to attend the event in New York Tuesday night.
Obama is expected to claim enough delegates to put him over the top that night at a separate event in St. Paul.
Earlier in the day it was reported that Clinton staffers were being urged by the campaign's finance department "to turn in their outstanding expense receipts by the end of the week," another sign that the run at the White House was nearing an end. In addition, Politico wrote that members of Clinton's advance staff had received calls and emails Sunday night, summoning them to New York City and telling them their roles on the campaign are ending.
