ABC News has lured Jack Ford from NBC, where he will be a host and correspondent on "20/20" and immediately becomes a leading candidate to replace Charles Gibson on "Good Morning America."

Ford has been the chief legal correspondent at NBC and co-anchor of the "Today" show's weekend editions.

He will report legal and other stories and anchor one night a week on the newsmagazine "20/20."

Ford will also sub regularly on "GMA," where Gibson returned hurriedly as host in January to stop a ratings free-fall. Gibson said he would stay with the morning show through the spring.

Both Ford and ABC News spokeswoman Eileen Murphy said no promises had been made that Ford will inherit Gibson's job. But Ford said it's an attractive position.

"If you said to anybody in the business, 'Would you like to be anchor of "Good Morning America"?' they would say, 'Absolutely,' " he said today.

A former prosecutor in Monmouth County, N.J., Ford began his television career as a legal commentator at New York's WCBS-TV in 1983. He was an anchor at Court TV from 1991 to 1994.

He'll leave "Today" following Saturday's edition. Sarah James and John Seigenthaler will be among the temporary co-hosts with Soledad O'Brien on "Today" until a permanent replacement is named for Ford.
