David Rivera says he raised more than $500,000 in the second quarter, bringing his total cash on hand to more than $1.1 million in the campaign for the seat vacated by Rep. Mario Diaz-Balart.
More than 80 percent of contributions were from individual donors and 70 percent didn't max out for the primary, allowing him to raise more money from them.
"I have been so fortunate to receive such strong support from my family, my friends and the voters in South Florida in this race so far," Rivera said. He said nearly half of his donors gave less than $500, below the limit of $2,400 per election.
Rivera's chief Democratic challenger, Joe Garcia, outraised him for the quarter, reporting earlier this week that he pulled in more than $700,000 in the latest quarter.
More detailed reports are due today.
