(CNN) - Hillary Clinton raised over $7.5 million online since February 1, $6.4 million of which has come in the last 24-30 hours, her campaign chairman announced Thursday.
That number appears to fall short of what rival Barack Obama has raised in the same timeframe. Earlier Thursday, the Illinois senator's campaign announced it had raised $7.2 million in the first 36 hours after polls closed on Super Tuesday.
"The grassroots in the last 24 hours or since Super Tuesday have really stepped up," Clinton Campaign Chairman Terry McAuliffe said on a conference call with supporters. "It has been spectacular, it has been a huge outpouring of support."
He also said that since Super Tuesday, the campaign has seen 40,000 new online donors.
McAuliffe suggested the news of Clinton's decision to loan herself $5 million in January was a chief reason for the heightened fundraising haul, saying many supporters were unaware the campaign was in need of cash.
He also said all campaign staff was now being fully paid, following reports some senior staff members had voluntarily offered to forgo pay for a month.
The campaign will begin to air television ads in Washington State, Nebraska, Maine – states which are set to hold nominating contests this weekend. It will also begin airing ads in Ohio and Texas next week ahead of the March 4 primaries in those states.
