The WSJ reports that Sen. Clinton has forgiven about $13 million in personal loans she made to her campaign for president.  Bloomberg also has an article.   Campaign finance law contains a provision addressing candidate loans over $250,000 and the opportunity for repayment.

(b) For personal loans that, in the aggregate, exceed $250,000 in
connection with an election, the authorized committee:
(1) May repay the entire amount of the personal loans using contributions to the candidate or the candidate’s authorized committee provided that those contributions were made on the day of the election or before;
(2) May repay up to $250,000 of the personal loans from contributions made to the candidate or the candidate’s authorized committee after the date of the election; and
(3) Must not repay, directly or indirectly, the aggregate amount of the personal loans that exceeds $250,000, from contributions to the candidate or the candidate’s authorized committee if those contributions were made after the date of the election.
(c) If the aggregate outstanding balance of the personal loans exceeds $250,000 after the election, the authorized political committee must comply with the following conditions:
(1) If the authorized committee uses the amount of cash on hand as of the day after the election to repay all or part of the personal loans, it must do so within 20 days of the election.
(2) Within 20 days of the election date, the authorized committee must treat the portion of the aggregate outstanding balance of the personal loans that exceeds $250,000 minus the amount of cash on hand as of the day after the election used to repay the loan as a contribution by the candidate.
(3) The candidate’s principal campaign committee must report the transactions in paragraphs (c)(1) and (c)(2) of this section in the first report scheduled to be filed after the election pursuant to 11 CFR 104.5(a) or (b).
