In January, the Romney campaign and the super PAC supporting him brought in $13.1 million in January, but spent $32.7 million in the same month, Politico reported Friday.
Now, Romney is reaching out to his supporters in Congress for extra cash.
Romney asked the 80 Republican lawmakers who have endorsed him to raise $10,000 each for a fundraiser at the end of the month in Washington.
"We need your support to ensure it is a big success," wrote Missouri Sen. Roy Blunt in an e-mail to colleagues about the fundraiser. "Take this opportunity to reach out to your best supporters, and ask them to commit to this special event."
Blunt told Politico the Romney campaign is confident the fundraiser, scheduled for March 22, will bring in significant member support.
"In this case, with a fundraiser substantially driven by members, the governor has an opportunity to strengthen his relationships now," Blunt said. "It's important for the governor to have time with members and for members to be financially committed to the campaign as well as politically."
Meanwhile, Romney was on the campaign trail in Mississippi and Alabama ahead of primaries next week, USA Today reported.
"I am learning to say y'all and I like grits, and things," Romney said to a crowd Thursday. "Strange things are happening to me."
Romney admitted he feels out of his element in the south, saying, "I realize it's a bit of an away game."
