Luke Bryan is asking his fans for their support for a Giving Tuesday campaign that is very close to his heart. Luke is raising funds for the “Brett Boyer Foundation” in honor of his niece, who died in February of 2017.

The foundation was created in honor of Sadie Brett Boyer. She was the daughter of Luke’s wife Caroline’s brother, Bo Boyer, and his wife, Ellen. She was born with Down Syndrome and suffered from congenital heart disease (CHD), and died at the age of seven months.

In a Facebook video, Luke and Caroline talk soberly about the fundraiser, with him noting that the death rates from CHD have declined by more than 30 percent over the course of the last decade.

“But we want to do better,” he says, before insisting, “We can do better.”

The fundraiser had raised $1,618 of its $5,000 goal within hours of him posting it to Facebook yesterday.
