U.S. Rep. Don Young is engaged.

The 81-year-old introduced Anne Garland Walton as his fiancee, to applause, during "Candidate Sunday" at an Anchorage mega-church on Sunday.

Young spokesman Matt Shuckerow said the congressman attends the church, Anchorage Baptist Temple, when he is in town.

Walton, a flight nurse from Fairbanks, said later that no date had been set. She said the engagement has been unofficial for some time.

Shuckerow said Walton is in her 70s.

Young is a widower; his wife, Lu, died in 2009.

Young is currently the longest serving Republican in the U.S. House. He is seeking his 22nd term.
