Haushalter said it's understandable why those records could be "misconstrued" to view the spay-neuter clinics as taxpayer-funded.
She said that CPPW reports include all the group's work, "collaborative" and otherwise, and other activities of interest.
"Nashville has been selected for an HBO documentary about 'Obesity in America,'" one entry reads.
"Services ... occurred to provide free spay/neuter and wellness clinics for dogs and cats in order to curb animals running at large," the entry cited by Energy and Commerce Republicans states.
"The spay-neuter clinic was a project that we convened and supported, but that the Humane Association funded," Haushalter repeated.
"We can assure you no taxpayer funds were used."
A video by The Tennessean dated Feb. 9 appears to support this version of the story.
CPPW "is working on an educational campaign promoting responsible pet ownership, the importance of spay-neuter, proper pet confinement as well as the leash laws in Davidson County," a man identified as a Nashville public health worker told the camera.
"And the Nashville Humane Association, one of our partners, is working on a PetSmart Charities grant that provides free targeted spay-neuter to residents," he said.
