The mother-of-five told housemates in Celebrity Big Brother that Harvey, 12, is driven to and from school every day, with the taxpayer funding the driver costs and costs of a daily nurse.
Her comment sparked headlines and debate over whether the multi-millionaire should pay for the costs from her own pocket or whether it's right that the taxpayer should pay.
Today, her brother Danny spoke out to thank the public for supporting Katie and agreeing that Harvey had every right to get the necessary support allowed by law.
He tweeted: "As a brother to Kate and as a proud uncle to Harvey, I just want to say thank you all for the overwhelming support on an issue that really shouldn't have required any justification in the first place."
Danny also referred to his mum Amy's piece in The Sun today, in which she said Harvey is entitled to the care just as other disabled children would be.
She said Harvey needed to travel 50 miles to school every day and 50 miles back as his local special school had been closed. The family had campaigned to open a free school in its place but this didn't happen.
Now, the Local Authority had assessed and agreed that the school 50 miles away was Harvey's best option in line with his Statement of Special Educational Needs.
A statement issued to Katie's website added that the cost of school placement and transport is not means tested as it's provided for the child. He requires the nurse to travel with him because of his life threatening conditions that could require an emergency injection.
Harvey has disorders affection his appetite and growth, as well as being visually impaired and having ADHD.
