CLAREMORE, Okla. (AP) -- An Oklahoma hospital executive says country singer Garth Brooks considered giving $15 million to his facility if it would name itself after his late mother.

Brooks is suing the Integris (in-TEHG-rihs) Canadian Valley Regional Hospital, saying it wouldn't name a women's center for Colleen Brooks after receiving $500,000 from him.

The Tulsa World (http://bit.ly/Avdi1z ) reports that hospital president James Moore testified Wednesday that discussions initially involved a much larger gift.

An internal document from the hospital quotes Brooks as saying a $15 million gift for naming rights was "exactly" what he had in mind. Moore says he never spoke to Brooks about naming a women's center for a half-million dollars.

The hospital considers Brooks' donation unconditional.

Colleen Brooks died of cancer in 1999. A women's center never was built.
