Moments after the Obama campaign announced that it had raised $40 million in the month of March, Clinton spokesman Howard Wolfson told reporters on a campaign conference call that the New York senator's fundraising figures for that month would not be released until April 20 - the official FEC deadline, two days before the Pennsylvania primary.
"We knew that he was going to outraise us, he has outraised us for the last several months," said Wolfson. "We will have the resources that we need to compete and be successful in the upcoming primary states."
He said the Obama campaign had already outspent Clinton's in Pennsylvania about 4-to-1 and that he expected her campaign would be outspent about 2-to-1 on TV ad buys going forward.
Wolfson added that they expected Clinton's tax returns to be released within the one-week time frame she had promised. Clinton actually made the pledge eight days ago.
