The most recent three loans Clinton made came in addition to the $5 million she loaned the campaign in late January, Newsday reported.
"Senator Clinton gave the campaign a $5 million loan on April 11, a $1 million loan on May 1 and $400,000 loan on May 5," said campaign strategist Howard Wolfson. "She is willing to do so going forward to make sure our message gets out."
After eking a win in the Indiana primary over Sen. Barack Obama, D-Ill., and losing lopsidedly in the North Carolina contest Tuesday, Clinton canceled television appearances Wednesday, instead scheduling an appearance in West Virginia, the next primary stop.
Wolfson said the campaign has had "no discussions" about Clinton dropping out.
West Virginia's primary Tuesday is the first of the handful of remaining Democratic presidential preference contests.
