The National Republican Congressional Committee raised $30 million for its largest fundraiser of the year, which is being headlined by President Donald Trump Tuesday night in Washington, D.C. 

The haul for this year’s March Dinner, obtained first by Roll Call, breaks the $20.5 million record set at last year’s dinner. 

Mitt Romney headlined last year’s dinner during the contentious 2016 presidential primary, when many congressional Republicans still didn’t want anything to do with Trump. 

But since Trump’s victory, the House GOP’s campaign arm has had a successful fundraising year, which its leaders have chalked up to excitement about having an all-Republican government. The NRCC this year topped its previous fundraising records for January and February. 

“This level of financial support for our annual March Dinner is unprecedented,” said Arkansas Rep. Steve Womack, chairman of the March Dinner. 

“People are rallying around House Republicans as we work to solve the immense challenges facing our country,” Womack added. 

Trump’s appearance at Tuesday’s dinner comes at crucial time for leadership, which is still trying to whip members on its health care plan ahead of an anticipated vote Thursday that will test the president’s political capital. 

Trump will keynote the fundraiser, held at the National Building Museum, hours after meeting at the White House with some members of the Tuesday Group, several of whom have signaled their opposition to the bill. In a Tuesday morning meeting on Capitol Hill, Trump warned the GOP conference of the political risk of killing the plan.
