President Trump raised $24.8 million in less than 24 hours as he officially launched his reelection, GOP officials said Wednesday, underscoring the huge fundraising lead the president has over a crowded Democratic primary field.

The Wednesday announcement by Republican National Committee Chairwoman Ronna McDaniel, confirmed by campaign officials, indicates that Trump is on track to report his best fundraising quarter since he became president.

The one-day haul as Trump held a kickoff rally in Orlando included $14 million for Trump’s reelection committee and $10 million that went to Trump Victory, a joint fundraising committee between his campaign and the RNC that can accept large donations.

The president appeared at a high-dollar fundraising luncheon at the Trump National Doral hotel in Florida on Wednesday, which officials said raised about $6 million.

In all, officials raised close to $30 million in a two-day period — nearly as much as the $39 million he raised in the first three months of this year. The flood of cash is helping his campaign quickly expand its staff and finance an early barrage of online ads.

The president’s fundraising bonanza this week far eclipsed the $6.3 million that former vice president Joe Biden’s campaign said it pulled in on the day of his late April campaign announcement — the largest 24-hour amount raised by any of the Democratic campaigns this year.

In 2016, Sen. Bernie Sanders brought in $6.5 million in the 24 hours after the New Hampshire polls closed, at the time a single-day record for his bid that helped make him financially competitive with Hillary Clinton. For his 2020 bid, Sanders raised $5.9 million on the day of his launch.

“This is going to put fuel in the president’s engine to go through November 2020,” said Roy Bailey, a GOP donor and national finance co-chairman for Trump’s reelection bid. “Whatever the Democrats are raising, they’re going to eat up and burn all that fuel in the primary fight.”

Trump’s reelection operation is financially dominating the Democratic field of two dozen primary candidates, each trying to break out from the pack and gain fundraising momentum. Some Democratic candidates pointed to Trump’s totals in an effort to persuade supporters to give more.

“Donald Trump launched his 2020 campaign last night and he’s already raised a frightening amount of money,” read a fundraising solicitation from the campaign of former congressman Beto O’Rourke of Texas.

Julianna Smoot, a Democratic fundraiser who led Barack Obama’s campaign finance team in 2008 and was deputy campaign manager in 2012, called Trump’s haul “impressive” but said Democratic fundraising will ignite once a nominee is chosen.

“The issue is going to be, frankly, how we narrow that down sooner rather than later because as you can see, Trump is raising so much money,” she said. “We just can’t be outspent up until next year when the nominee is determined.”

Unlike his predecessors, Trump began fundraising for his reelection as soon as he became president, drawing on the loyal base of small donors he built in 2016.

And he has another big edge: as an incumbent president, Trump benefits from big-money contributions that flow through the Trump Victory committee to the national party, which is already working for his reelection.

While donors are capped at $5,600 per cycle to a candidate, they can contribute as much as $710,000 to national parties in the two-year period.

“They basically have Trump Victory way before the Democrats have a candidate. That’s a huge advantage,” said Ron Weiser, a GOP donor and Trump fundraiser.

Trump has raised more money than any previous president at this point. So far, the biggest quarterly total reported by the Trump campaign and its affiliated committees was $39 million in the first quarter of this year.

Campaign officials have said they have a goal of spending at least $1 billion in the 2020 cycle.

The reelection campaign, working in concert with the RNC, has used its resources to hire dozens of communications officials, political advisers and consultants, who work from three offices in New York, Virginia and Washington. It has 80 paid consultants and full-time staff members, a number that campaign officials said would be growing soon.

The reelection operation has collected data from hundreds of thousands of potential voters, according to several campaign officials familiar with the data effort. The campaign is seeking to amass 2 million volunteers by Election Day, campaign officials have said.

And because of the abundance of cash, the campaign is eying states such as New Hampshire, New Mexico and Nevada as possible pickups in 2020, campaign officials said. Democrats have won and increased their power in all three since 2016.

“He’s in a better position today than when he won in 2016,” said Brian Walsh, president of America First Action, a pro-Trump super PAC that is also raising money to fund opposition research against Trump’s potential opponents. “He’s got a very sound and mature, modern political operation behind him.”

Even though he has been actively fundraising for his reelection since last year, Trump used his rally Tuesday as an official kickoff. Throughout the day, the campaign and affiliated fundraising committees peppered supporters with text and email messages urging them to donate online toward his first-day total.

“They underestimated me, but more importantly, they underestimated YOU. Your support has been the fuel to our success,” one email solicitation Tuesday read. “Tonight I’m officially launching my Second Term Presidential Run and I want YOU to be on my side.”

The Trump campaign also held a telephone drive in Orlando on Tuesday to raise money for the reelection, Bailey said. About 200 people participated, he said, including Texas Lt. Gov. Dan Patrick (R), the president’s eldest two sons, former Fox News host Kimberly Guilfoyle and senior adviser to the 2020 campaign and RNC finance chairman Todd Ricketts.

Trump’s in-person fundraising schedule has also picked up this year, with stops in the District, California, Texas and Florida. During a donor retreat in Palm Beach, Fla., in March, Trump’s reelection effort was slated to bring in at least $7 million over the course of a weekend, a Republican Party official said.

Trump has complained to some advisers about doing so many fundraisers, but he has kept pace — including with several events at properties he owns.

Correction: Due to incorrect figures provided by the campaign, this story originally stated that the $24.8 million announcement did not include the money raised from the Doral fundraiser. The total did include the projections for the fundraiser held at Doral on June 19. The total raised within the two-day period surrounding Trump’s official kickoff was about $28.8 million, according to campaign and GOP officials. This story has been updated to reflect the new information provided by the campaign and RNC after it was published.
