As a member of the Senate Intelligence Committee from 1993-2000, Kerry missed 38 of 49 public hearings, or just over 76%. Senator Kerry has refused to reveal what percentage of the closed meetings he has attended.
In the year following the 1993 attack on the World Trade Center, Senator Kerry did not attent a single public meeting of the Senate Intelligence Committee.
In 2004, Senator Kerry missed over 80% of all Senate votes.
