Donald Trump’s boasts in the primary season that he would largely fund his own presidential campaign have slowly given way to more traditional methods of campaign finance as he’s pivoted to the general election. Over the past several weeks, Trump has insinuated that he would need to raise outside money and depend on the Republican Party for funding. And on Saturday, Trump’s campaign released an “emergency” fund-raising email, CNN reports.

“Right now we’re facing an emergency goal of $100,000 to help get our ads on the air,” the email said. “We need your contribution by 11:59 P.M. Tonight.”

The urgent email was sent in response to an ad blitz from Hillary Clinton’s campaign and promises that with funding, Trump’s campaign will release attack ads against Clinton focusing on her role in Benghazi, her email scandal, and details of her campaign donors. Clinton’s campaign released its first general election ad recently, targeting Trump for egging on violence at his rallies and mocking a disabled reporter.

“Crooked Hillary is about to invade your TV with ads attacking Mr. Trump,” the email said. “But we’re preparing to fight back.”

It is normal for presidential candidates to release emails in this fashion, but Trump’s emergency blast reinforces his evolving approach to fundraising. Senior Trump advisor Paul Manafort told Senate Republicans in May that Trump will depend more on the Republican Party during the general election. Without the party’s help, he won’t be able to run television ads in response to attacks from the Democratic Party.

Trump is not shying away now from publicly asking the Republican Party for money, saying that if the GOP doesn’t group to support him, he will stop fundraising for the party and continue paying for his campaign.

“Life is like a two way street, right?” Trump said at a Las Vegas Rally on Saturday. “Otherwise I'll just keep doing what I'm doing. I'll just keep funding my own campaign. I'm ok with that. That's the easy way. I mean for me, that's the easy way. But, hopefully I can continue to go the way we're going, and this weekend we raised a lot of money. We've raised a lot of money for the Republican Party. We'll keep doing it, because we do have tremendous support within the party that I can tell you.”
