(CNN) - Mitt Romney's campaign said Thursday they had a behemoth fund-raising month in June, bringing in more than $100 million, two Republican sources confirmed.
The amount, which includes money raised by the campaign along with the Republican National Committee, far surpasses his May fund-raising haul of $77 million.

In the last month, Romney has made several big fund-raising trips, including stops in California, Oregon, Washington and Texas. In the Lone Star State, alone, he was expected to have raised $15 million in his two-day trip.
Also in June, he was expected to have had his highest day ever while in his native state of Michigan for a pair of fund-raising events on June 20, raising between $6 and $8 million.
And the campaign underwent a fund-raising boom in the hours after the Supreme Court ruled to uphold the controversial health care law that Romney and Republicans vehemently stand against. Less than 24 hours after the high court announced its decision, Romney's camp took in more than $4.6 million online from over 47,000 contributors.
Obama's team has repeatedly said they expect to be out-raised by Romney in June, with some campaign officials even predicting Romney would hit the $100 million mark.
"I think Romney's going to continue to have big months. Combine that with the super PAC stuff and we're going to be the first incumbent outspent. That's clear," one official, who, along with other top members of the re-election team, spoke to reporters on background in mid June.
It is likely that this will be the second month in a row the presumptive GOP nominee takes in more cash than the president. In May, the Obama Victory Fund brought in $60 million.
The Republican effort said they ended May with $107 million in the bank. Obama's campaign finished the month with slightly less than $110 million.
Ben LaBolt, a spokesman for Obama's campaign, reacted to Romney's fundraising numbers, saying, "Mitt Romney is trying to distract from a week when he took contradictory positions on the freeloader penalty in the Affordable Care Act and we learned more about his offshored finances in Switzerland, Bermuda, and the Cayman Islands.
"Americans are less concerned about how much money he raised to get himself elected and more interested in what he would do after repealing health reform, which he has refused to share, and why he won't disclose the necessary tax returns that prove whether or not he paid any U.S. taxes on his shell corporation in Bermuda," LaBolt continued.
Both campaigns have until July 15th to officially report their fund-raising numbers to the Federal Election Commission.
Politico was the first to report Romney's numbers.
