The incumbent and challenger in this year's race for U.S. Senate each are reporting $1 million-plus fundraising totals for the second quarter.

Sen. Bob Menendez, the incumbent Democrat from Hudson County, raised $1.7 million for the quarter that ended June 30, bringing his total cash on hand to $10.3 million.

Joe Kyrillos, the veteran Monmouth County state legislator who is the Republican challenger, raised $1.3 million for the quarter, bringing his cash on hand to $2 million.

Each candidate raised more than $1 million in the first quarter. Experts say a competitive U.S. Senate race will cost more than $8 million to run.

Kyrillos campaign manager Chapin Fay says Menendez is getting big donations from oil companies and Wall Street firms. Menendez's camp says "corporations and billionaires" may fund Kyrillos.
