President-elect Donald Trump didn't need $100 million of his money to win the White House in the end.

Trump contributed another $10 million to his presidential campaign in the closing days of the election, bringing his total investment in the race to $66.1 million, new filings confirm.

Trump’s campaign still had $7.6 million in leftover money in its bank account as of Nov. 28, as the real-estate magnate defied most conventions about political spending and advertising on his way to capturing the presidency.

Nearly 74% of the money he raised in the election’s homestretch and immediate aftermath came from small donors, according to the report his campaign filed late Thursday with the Federal Election Commission. It covered activity from Oct. 20 through Nov. 28.

Some big donors aided his candidacy, too. Tech billionaire Peter Thiel, who is playing a key role in Trump’s transition, donated $1 million in late October to Make America Number 1, a pro-Trump super PAC aligned with New York hedge-fund billionaire Robert Mercer and his daughter Rebekah.

In the final days of the campaign, former political rival Ben Carson, whom Trump has tapped to serve as head of his Department of Housing and Urban Development, transferred $100,000 in leftover funds from his presidential campaign to Make America Number 1.

Some of Trump's biggest checks went to his web marketing firm, Giles-Parscale, which waged an under-the-radar digital campaign to target voters in key states.
