BOSTON (AP) — A group of well-known journalists will pay tribute to the late U.S. House Speaker Thomas P. ‘‘Tip’’ O'Neill during a forum at the John F. Kennedy Presidential Library and Museum.

Journalists Al Hunt, Cokie Roberts, Mike Barnicle and Chris Matthews will share their memories of O'Neill during a forum with former ‘‘ABC World News’’ host Charlie Gibson on Sunday, the centennial of O'Neill’s birth.

O'Neill, a Democrat from Massachusetts, served as speaker from 1977 to 1987. He represented his Boston-area district from 1953 to 1987.
