Donald Trump's campaign has alerted Senate Republicans that he won't have much money to spend fending off attacks from Hillary Clinton over the next couple months.

The notice came when Paul Manafort, Trump's senior advisor, met with a group of Senate Republican chiefs of staff for lunch last week, sources familiar with the meeting told the Washington Examiner. The admission suggests that Trump will be far more dependent on the GOP brass for money than he has led voters to believe, but it's consistent with his reliance on the Republican National Committee to provide a ground game in battleground states.

"They know that they're not going to have enough money to be on TV in June and probably most of July, until they actually accept the nomination and get RNC funds, so they plan to just use earned media to compete on the airwaves," one GOP source familiar with Manafort's comments told the Examiner.

That's a far cry from Trump's public insistence that he signed a fundraising agreement with the RNC in order to help the party, not himself. "The RNC really wanted to do it, and I want to show good spirit," he said last week. "'Cause I was very happy to continue to go along the way I was."

Still, Trump allies have suggested that the RNC is going to take advantage of the real estate mogul. "I don't think the RNC is 100 percent committed," a GOP donor told CNN. "If Donald Trump's seven points down in October, they're going to put that money toward Senate races and House races."

Manafort seemed confident at the lunch with GOP staff, however. "He said that he thought Hillary Clinton was the ideal opponent — that he was the ultimate outsider and she was the ultimate insider," a Senate GOP chief-of-staff in attendance said.
