Sen. Marco Rubio pulled in $12 million for his presidential bid, the Florida Republican's campaign revealed Monday.

The haul included a $3.3 million transfer from Rubio's Senate campaign account. But donors to that committee were effectively converted into contributors to Rubio's presidential bid. That means any individual who gave the maximum $2,700 allowed by law to Rubio's Senate account is now considered a maxed out donor to his White House campaign. Rubio, 44, raised $900,000 into his Senate committee in the first quarter of 2014, closing that period with $4 million in the bank.

Rubio announced for president on April 13, roughly two weeks into the second quarter fundraising period. During that time, the senator's political action committee, Reclaim America, raised $1.2 million, bringing his total April-to-June haul to $13.2 million.

Meanwhile, Rubio's campaign touted 12,000 Florida donors who contributed a total of $2.2 million to his 2016 campaign. It's unclear how that performance compares to former Florida Gov. Jeb Bush's Sunshine State total. Bush raised more than $11 million for his presidential campaign during the final two weeks of the second quarter.

All told, Rubio entered July with $9.72 million in cash on hand in his presidential campaign account and $539,000 available to spend from his leadership PAC, putting him near the top of the crowded Republican presidential money chase. He trailed Bush and Sen. Ted Cruz of Texas, who entered the race in the final week of the first quarter and brought in more than $14 million, but led all other contenders who have publicized their second quarter, hard-dollar campaign numbers.

"The campaign received donations from all 50 states, as well as the District of Columbia, Guam, the Northern Mariana Islands, Puerto Rico, and the Virgin Islands," the Rubio campaign said in a press release. "The median donation is $50 and the campaign's most frequent donation amount is $25. Rubio's support was especially strong in his home state of Florida, where more than 12,000 donors contributed a total of $2.2 million to his presidential campaign."

Rubio's presidential aspirations are additionally supported by a super PAC and affiliated nonprofit organization that together raised approximately $16 million, each, through June 30.
