Donald Trump’s campaign is expecting to raise more than $40 million on Saturday when major donors gather for his biggest fundraiser yet.

The event at the Palm Beach, Florida, home of billionaire investor John Paulson is expected to bring in $43 million for the former president’s third run at the White House, according to Paulson.

The high-dollar event is expected to include about 100 guests, including more than a few billionaires, and top a new single-event fundraising record set by President Joe Biden, who raised $26 million recently at a gathering with former Presidents Bill Clinton and Barack Obama.

“The response to our fundraising efforts has been overwhelming, and we’ve raised over $43 million so far,” Paulson, a hedge fund manager, said in a statement. “There is massive support amongst a broad spectrum of donors.”

The event, billed as the “Inaugural Leadership Dinner,” sends a signal of a resurgence of Trump and the Republican Party’s fundraising, which has struggled to catch up to Biden and the Democrats.

Trump and the GOP announced earlier in the week that they raised more than $65.6 million in March and closed out the month with $93.1 million. Biden and the Democrats announced Saturday that they took in more than $90 million last month and had $192 million-plus on hand.

“While Donald Trump has been busy awarding himself golf trophies at Mar-a-Lago and palling around with billionaires, Joe Biden has been crisscrossing the nation connecting with voters and outlining his vision to grow our economy from the bottom up and the middle out,” Democratic National Committee Chair Jaime Harrison said in a statement, referring to Trump’s Florida residence.

Trump initially struggled to attract big donors in particular when he launched his campaign and some lined up to support the other Republicans who challenged him in the presidential primary. But as Trump racked up easy wins, leveled the field and became the party’s presumptive nominee, the GOP has solidified behind him.
