Trump aides say that option is not currently under discussion, NBC News has learned, but they also decline to rule out the possibility entirely.

Legally, Trump has the option of recouping any or all of the money he spent on the primaries.

That is because Trump almost never directly donates funds to his campaign. He has only spent about $317,000 of his own money outright.

The rest of his personal spending is structured as a loan to the campaign, which now owes Trump $35.9 million.

Those loans comprise about 75 percent of the campaign’s total funds.
