Two tickets to the event are being reserved for grassroots supporters, according to a fundraising pitch Warren's campaign sent to supporters on Friday. Those who donate $5 or more will have a chance at the tickets.

"Our campaign will handle any air transportation and accommodations — you just need to pick who you're going to bring with you," wrote Michael Pratt, Warren's finance director.

Warren has been the standout fundraising juggernaut of the 2012 cycle, surpassing what any other candidates have raised since she entered the race. Warren raised almost $7 million in the first three months of 2012.
