Hotline just came out with a copy of an earmark request that John McCain made. I found out about it from an Obama campaign press release.
Sen. John McCain, R-Ariz., has said repeatedly on the campaign trail that he never requested, or received, an earmark in annual appropriations bills during his 22 years in the Senate. My friends, it's just not so.
In April 1989, McCain sent a letter to then-Sen. James McClure, R-Idaho, asking the ranking Re-publican on the Senate Interior Appropriations Subcommittee for a set-aside to help restore a 200-year-old Catholic mission near Tucson, Ariz. "I would like to ask your help in the vital effort to restore San Xavier del Bac, by earmarking $500,000 for that purpose in the FY 1990 appropriations bill," McCain wrote in the signed letter, which is in McClure's archived papers at the University of Idaho.
