President Trump has agreed to donate a portion of his reelection funds to 100 GOP candidates running in competitive House and Senate races, his campaign announced Thursday, noting that other candidates are expected to receive contributions before the November midterm elections.

The announcement comes one day after a Quinnipiac University poll found Democratic candidates were favored 51 percent to 39 percent on a generic House ballot, a startling sign for the White House and many incumbent Republicans.

In a statement, Trump campaign chief Brad Parscale said the president's decision to open his coffers to Republican candidates was aimed at boosting those "[m]embers of Congress so we can maintain the momentum of the Trump agenda, including record job creation and economic growth."

"This is just one step in our plans to commit our resources and strategic support to these campaigns in the mid-terms," Parscale added. "We are all in to win this year for President Trump and the American people."

The National Republican Senatorial Committee and National Republican Congressional Committee will receive $4 million each as part of the transfer from Trump's re-election campaign, Republican National Committee Chairwoman Ronna McDaniel said Thursday. Overall, the RNC is expected to spend nearly $250 million in the fight to maintain the party's majority in Congress and boost the number of Republican officials serving at the state level.

"Thanks to President Trump and our supporters, we have the resources to protect and strengthen our Republican majorities in Congress," McDaniel said.
