The Romney Victory Fund, announced on April 4, is a joint fundraising effort by the Romney campaign and the Republican National Committee.
The campaign announced on Thursday that it had raised more than $40.1 million in April, a spike from $12.5 million in March. The campaign said it had $61.4 million in cash on hand.
Romney spent $45 million of his own funds for his unsuccessful 2008 run. Until now he has not spent his own money for the current election campaign.
Romney and his wife's donations, while significant and symbolic, are small in comparison to the six- and seven- figure donations by others to the super PAC supporting the candidate, Restore Our Future.
