WASHINGTON — Democrat Hillary Rodham Clinton has reported a $22.5 million debt at the end of May, more than half of which is from personal loans to her presidential campaign.

The former first lady, who ended her campaign June 7, received contributions of $12.6 million in May. She lent her campaign nearly $2.2 million during the month, bringing her total personal investment in the campaign to $12.175 million.

Clinton had $3.4 million cash on hand left for primary spending. She also had $23.3 million for the general election, money her campaign cannot use to pay off her primary debt.
