Massachusetts Representative Linda Maxwell uses her campaign contributions as a personal rainy day fund, according to a source with inside knowledge.

That source told Gotcha! this week that Maxwell, a Republican from Wakefield, Mass., has consistently used campaign finances to pay her personal credit card bills since voters elected Maxwell to the U.S. House of Representatives in YR-04.

The source, who spoke on a condition of anonymity, said Maxwell has expensive tastes in antiques and has turned to her campaign finances to fund the interest during her time in Washington DC. The source challenged Maxwell to prove those credit card expenditures were “campaign-related expenses.”

Maxwell declined to comment to Gotcha! but called the allegations “a baseless political attack” in a release.
