Nikki Haley, the former South Carolina governor and United Nations ambassador, raised $7.3 million through her presidential campaign and affiliated committees from April through June, a modest sum that still showcased her robust appeal to small donors.
The total included $5.3 million reported by her campaign, as well as money from two allied committees, according to reports provided by her campaign to The New York Times in advance of a filing deadline with the Federal Election Commission on Saturday.
Separately, a super PAC supporting her candidacy said on Monday that it had raised $18.7 million since its inception this year, and that it had $17 million in cash on hand at the end of June. Reports for super PACs are not due with the F.E.C. until the end of the month.
Her campaign’s fund-raising numbers fell below those of the two men leading the polls for the Republican nomination, Gov. Ron DeSantis of Florida and former President Donald J. Trump. Last week, the DeSantis campaign said it had raised $20 million, while a super PAC supporting him had raised $130 million since March.
Mr. Trump’s joint fund-raising committee, his primary fund-raising vehicle, said it had raised $35 million in the second quarter; it is not clear how much went to his campaign committee.
Neither the Trump campaign nor the DeSantis campaign provided the reports. When they are filed this weekend, they will provide greater clarity on how each candidate’s money has been raised and spent.
By her campaign’s account, Ms. Haley is above the minimum threshold of 40,000 individual donors that candidates must reach to take part in the first Republican debate on Aug. 23. Her campaign said it had received 160,000 donations from all 50 states since she entered the race in February, the vast majority of which were under $200.
Ms. Haley raised money through three committees: her presidential campaign, a joint fund-raising committee called Team Stand for America, and a multicandidate PAC. The joint fund-raising committee also transfers money to the other two committees — the $5.3 million received by her campaign in the second quarter, for example, includes a $1 million transfer from Team Stand for America.
In April, Ms. Haley came under criticism after her campaign broadcast that $11 million had been raised in its opening six weeks. In fact, the committees had together taken in about $8.3 million, including $2.7 million in transferred money that was counted twice.
Together, the three committees had $9.3 million in cash on hand at the end of June, according to the latest filings; her campaign accounts for $6.8 million of that.
