The RNC reports raising $5.7 million in May, leaving the committee with $21.5 million cash-on-hand "and zero debt."

"I am pleased that the Republican National Committee continues to show solid fundraising numbers, and we are grateful to the countless Americans who have contributed to our Party. We have important and competitive elections this fall and next year. With another month of strong fundraising numbers, we are confident and well positioned to win," said RNC Chairman Michael Steele.

The party had raised $5.8 million in April and ended the month with $24.4 million on hand.
