Details for unity rally

Barack Obama's campaign has released more details of the big rally in Unity. N.H., on Friday.

It will be outside Unity Elementary School, and the gates will open at 11 a.m. The exact time the event will start is pending Secret Service approval, but is expected to be in early afternoon.

The event -- the first joint general election campaign rally with Obama and former rival Hillary Clinton -- is open to the public, but tickets are required. They can be obtained at the campaign website.

There is no onsite parking; instead there will be shuttle buses from two nearby sites: the Mount Sunapee Resort in Newbury and Twin State Speedway in Claremont. The buses will start running at 10 a.m.

An estimated 2,500 people are expected, surpassing the town's year-round population of 1,700.

In advance of the rally, Obama asked his top fund-raisers to help Clinton pay off her debt, the Associated Press is reporting.

Obama on Tuesday asked his finance team to help Clinton pay back at least $10 million. At the end of last month, she owed a little more than $10 million to outside vendors, and also had more than $12 million in loans she gave her own campaign.

Donors who have not contributed to Clinton's campaign could give up to $2,300 each to help her pay off her debts.

In a statement issued by her office, Clinton thanked Obama: "Senator Clinton appreciates Senator Obama’s generous efforts and is continuing her efforts to raising the moneys he needs to ensure a victory in November."

UPDATE: In an e-mail to supporters today, Clinton asked again for help repaying vendors and said she wouldn't use their money to repay herself.

"As you know, I had to loan money to my campaign at critical moments," Clinton wrote. "I'm not asking anyone's help paying that back. That was my investment and my commitment because I believe so deeply in our cause."
