WASHINGTON (CNN) - Democrat Hillary Clinton has loaned her presidential race $6.4 million over the last month, bringing the total amount of money she has lent herself to $11.4 million.
And she is willing to lend herself more money, top adviser Howard Wolfson told reporters Wednesday, a day after Clinton eked out a narrow victory over Sen. Barack Obama in Indiana's Democratic primary but lost to him by a landslide in North Carolina.
The $11.4 million she has lent her campaign this year is about the same as the amount she earned from book sales and her Senate salary, Wolfson said.
On a conference call with reporters, Wolfson said the loan proves Clinton is committed to staying in the presidential race.
"The loans are a sign of her commitment to continuing the race, her commitment to continuing the process and her commitment to staying competitive with Senator Obama on television and other areas," he said.
"The campaign continues to raise a lot of money, but Senator Obama, to his credit, is also raising a lot of money."
Clinton loaned herself $5 million on April 11, $1 million on May 1 and $425,000 since then, the campaign said Wednesday. The senator from New York loaned her campaign $5 million in February.
Clinton began the month of April with close to $32 million in cash on hand, but only $9 million of that total could be spent during the primary season, according to the most recent campaign reports filed with the Federal Election Commission.
The report also showed that Clinton owed more than $10 million, meaning she was in the red even before she heavily stepped up television advertising ahead of the Pennsylvania primary in late April.
The day after her convincing Pennsylvania win on April 22, the Clinton campaign said it raised $10 million on the Internet. The campaign has not said how much it has raised since her close win in Indiana and her North Carolina loss Tuesday.
