Uh oh! It looks like she was taken shopping by Jeff Larson who was then reimbursed.
"Along with the matching dates and dollar totals, note the “Transaction ID Number,” which clearly connects the questionable expenditures with reimbursement payments made to Larson. (To totally wonk out for a second, the “m” stands for “memo,” which is included to provide an additional explanation of the transaction—basically, it links a disbursement with whatever was purchased.)

Does the name Jeff Larson sound familiar? It should. Larson is the Karl Rove protégé who’s a principal in the robocalling firm of FLS Connect (the “FLS” stands for Tony Feather, Jeff Larson, and Tom Syndhorst, all veteran Republican political operatives). Larson’s firm is the same one that launched the scurrilous robocalls against John McCain in 2000, and that McCain has now hired to make robocalls connecting Barack Obama to Bill Ayers. He’s also well known in Minnesota for leasing his basement apartment at a steeply discounted rate to embattled Republican Senator Norm Coleman. "
