NASHVILLE, Tenn. -- Former Senate Majority Leader Bill Frist and his wife of 31 years are splitting up.
Court records show Karyn Frist filed for divorce on Friday. A response filed for Bill Frist acknowledges irreconcilable differences.
Family spokeswoman Beth Seigenthaler Courtney declined to elaborate on the reasons for the split.
Bill Frist was a heart surgeon before entering politics in 1994. His 12 years in the Senate were marked by a speedy rise to leadership but an uncertain tenure.
In his 2009 memoir, Frist recounted meeting his future wife in 1979 when he attended to her at a clinic in Boston. He was engaged to another woman in Tennessee and broke it off a week before the wedding.
The Frists have three adult sons.
